Yen sun to open operation at China plants
Aaron Lee, Taipei; Joseph Tsai, DIGITIMES
Wednesday 20 February 2019
Taiwan-based cooling answer developer Yen solar know-how will espy its flowers in Dongguan quickly enter pilot creation for certification by means of its motor vehicle seller client and start mass construction in April with optimum means to gain over one million gadgets a month. The web site may live particularly used to meet orders from China, while flowers in southern Taiwan should live serving consumers from Europe, the us and Japan, based on Robert Liu, universal manager of Yen solar's digital Cooling Division.
Yen sun registered consolidated revenues of NT$290 million (US$9.33 million) for January, rising 17.seventy five% on year. on account of fewer working hours as a result of the Lunar original year vacation trips, the company expects the amount to glide on month in February, however to elect on up in March. Some market watchers forecast Yen solar's first-quarter consolidated revenues to gain a original quarterly checklist with contributions from cooling and residential appliance items.
Yen solar is planning to expand means at vegetation in southern Taiwan and has built original flowers in Dongguan, China to fulfill exact from the car sector.
Liu brought up that carriers are turning to hub of attention on designing cars with lighter weight and less vitality consumption and the approach is anticipated to set off a wave of exact for heat dissipation options. Yen sun's visibility of such orders has already reached the conclusion of 2019 and the enterprise is already starting to design automobiles with customers for the subsequent three years.
presently, Yen solar has 65% of its revenues contributed by means of its cooling answer products with the comfort coming from home appliance items. Of the revenues from cooling solutions, 38% are from automobile cooling and others workstation cooling.
currently, the flowers in southern Taiwan are capable of bear 120,000 contraptions of cooling fanatics a month and the company is looking to raise the quantity to 300,000 contraptions before the immediate of the primary half.

And it’s off to an excellent birth for the solar Flyer 2 and its Siemens electric motor. The electric powered plane (e-plane) effectively achieved its first gaze at various flight with the brand original electric motor.
Bye Aerospace has been diligent the past few years furiously working on this e-aircraft, so the executives engineers hold to live over the moon about the electric solar Flyer 2 completing its first respectable flight on February eight at the Centennial Airport, south of Denver, Colorado.
above all, Bye Aerospace is focusing its flight checking out on its propulsion equipment, envelope expansion, and techniques optimization. it is using a fifty seven lb Siemens SP70D electric motor, which has a max vitality of 89.5 kW (a hundred and twenty HP) and a ceaseless vitality atmosphere of as much as 70 kW (94 HP).
Bye Aerospace is setting up a few plane within the sun Flyer household — a 2-seat sun Flyer 2 and a four-seat sun Flyer 4, as they in the past said. The company wants to construct the first FAA-licensed, functional, all-electric powered airplanes to serve the flight practicing and common aviation markets.
Bye Aerospace competes with one more e-plane maker, Pipistrel, which has its Alpha Electro. dwell tuned for an interview with Pipistrel pros, as well as electric powered flight leaders at Bye Aerospace and Siemens.
The FAA gave the solar Flyer 2 a ways 23 certification closing year in 2018. Bye Aerospace will continue checking out of the solar Flyer 2 prototype through 2019.
related to this examine flight, in line with George E. Bye, CEO of Bye Aerospace: “The airplane performed exactly as planned. My due to the total Siemens crew for their participation as they enter this subsequent, essential flight check section of sun Flyer 2 with the Siemens electric propulsion device.”
The company too has 2 different projects, the Stratoairnet, a solar-electric powered Unmanned Aerial automobile (UAV) and the silent Falcon UAV developed by silent Falcon u.s.a.applied sciences which you can find perquisite here.Siemens’ chic position in the electric Aviation business
Siemens and its electric motors play a substantial role in the electric powered aviation world, a kindly deal love Bosch pushed alongside the electric powered bicycle (e-bike) world. Siemens has already verified 260 kW electric motors earlier than on European e-planes. The definitely respectable advice is that it’s establishing propulsion technology with a whopping 10MW of energy, for commercial electric plane for the aviation transport sector. to this point, Siemens electric motors hold set at the least two velocity facts — the primary aero tow via an electrical plane and a original world climb checklist with an altitude of three,000 meters in 4 minutes and 22 seconds.
Dr. candid Anton, government vice chairman and Head of eAircraft, Siemens delivered:
“This successful gaze at various flight is a supercilious second for the Siemens and Bye Aerospace teams and marks a milestone in bringing the age of electric powered flight to life. The Siemens electric powered propulsion apparatus offers a clear, cost-effective and silent propulsion preference to the flight training market devoid of compromising performance or safeguard.”electric Airplanes Are closer Than You think
The electric vehicle (EV) rEVolution has been significantly underway for the past decade, but generally focused on land-certain motors. The maritime and aviation industries are now working extra significantly on the electrification of vessels and plane, however in a unique approach from the automotive industry. but don’t live fooled just because you don’t yet espy a Tesla plane — Bye Aerospace and a brace of other electric flight pioneers are bringing electric powered urban air mobility near us.

One of the driving forces behind the prance to storage belt networks (SANs) has been the increasing flash and size of enterprise databases. As databases grew, administrators institute that the only way to efficiently manage and expand database storage is to tap into the flexibility of SANs. However, with the expanded exhaust of databases on storage networks, storage administrators now must deal with original performance, backup, restore and management issues-not to mention how to win along with the database administrators (DBAs). Here's what storage administrators should know about marrying a database to a SAN.Oracle's Storage Push In a sign that database vendors are increasingly aware of how indispensable the storage behind their databases is, Oracle recently announced that it is launching a storage initiative, which seeks to combine the company's various individual storage initiatives into a strategic thrust to focus on how Oracle runs on storage. Oracle's initiative includes programs to certify interoperability of hardware components within an Oracle environment.
According to Allen Hoke, technical director, system platforms division of Oracle, "This program focuses on storage technology at a tall plane vs. their former focus on specific areas such as backup or particular storage hardware or storage management technology." In addition, Hoke says, "In order to provide a kindly customer experience, they are teaming with their key OS, server hardware and storage partners to provide a remote back strategy, aligned between us and their partners."
At this time, Oracle's partners comprise EMC, HP, Hitachi, Network Appliance, Legato, Sun, and Veritas.
A few years ago, not many database applications ran on anything but direct-attached storage (DAS). As databases grew, however, administrators looked for easier ways to deploy storage and began using network-attached storage (NAS) to more easily scale their databases. With the advent of SANs, administrators are now finding that storage networks can provide even better performance for the most demanding transaction-oriented, tall volume databases.
Today, database applications are starting to prance from DAS to SANs. The reasons: increased ease and quicken of backup, better scalability, as well as enhanced reliability and performance. For many applications, a SAN is the only option available that provides the required performance.
Harold Durnford, a storage administrator at Royal Bank Canada, Toronto, Canada, says, "We've had Oracle, Sybase, UDB, and Informix on a SAN for quite some time. The intuition they looked at storage belt networks was the challenge of sharing big storage subsystems." In addition, he says, "It wasn't just a distance limitation, but too existent estate. With SCSI, they institute they quickly ran out of SCSI ports on their arrays before they ran out of storage. They used the SAN to address fan-out."
Marty Ward, vice president of product management at Veritas has too seen this, and says, "Database users are very focused on scaling up and scaling out, which you can't conclude with dedicated storage."
Bob Rogers, chief storage architect at BMC says, "Consistent plane of performance is driving people to storage belt networks, as are better character backup and recovery tools. Those are everything very sturdy motivators to proceed to a SAN environment, which is why very big customers hold embraced SANs and achieve databases on them quite early."
Jim Booth, director of systems engineering at CreekPath, agrees, saying, "People are pathetic to SANs primarily to win the performance. You can certainly implement a database on either NAS or a SAN. However, if you're doing it on a SAN, you win consistent throughput. Though it might live harder to manage, a SAN provides better performance and availability."
SAN configurationsA typical SAN configured for a database application includes database servers clustered for reliability and attached to a central network. At a minimum, two sever database servers are clustered together for redundancy, with dual redundant Fibre Channel (FC) fabrics connected to redundant RAID controllers. In many cases, path failover software such as EMC's PowerPath or Veritas' Dynamic Multipathing (DMP) is used to ensure multiple paths to the storage array, in conjunction with high-availability storage arrays and cluster software.
Michael Leo, a database administrator at Minneapolis, MN-based Caribou Lake Software, a consulting solid which helps companies manage their systems, works with a big medical devices manufacturer replacing legacy Alpha VMS systems with Solaris machines, connected to an EMC Symmetrix SAN. "Everything is striped and mirrored [1+0]. They are using the SAN for development, production online transaction processing [OLTP] and production reporting-a data warehouse of the production database used for reporting. Each database is in the 100GB to 200GB range. They hold two copies of the OLTP database-one is a replicated flaming standby, " says Leo. The systems flee Computer Associates' Ingres database.
"To back up the database, they are using the SAN for disk-to-disk backups. They then exhaust Veritas' NetBackup and a sever backup LAN to backup the SAN. To manage the disk space on the Sun, they exhaust Veritas in combination with EMC's SAN management tools," says Leo.
Database performanceOptimizing database performance has traditionally been done by configuring how and where tables and logs are stored, as well as configuring disks and storage for database access patterns. Database data is broken down into two principal types of data: tables-the actual data which is stored in the database-and logs, which are logs of the transactions to a database. Transaction logs are critical for recovering a database if there's a failure and are too used for replicating databases. Many databases can too exhaust their own autochthonous file systems to maximize performance, maintain control over tables and avoid potential performance penalties imposed by file system buffering. Aside from hastily storage, CPU and memory, administrators hold paid a lot of attention to balancing quicken vs. redundancy of data.
Database and storage administrators hold carefully selected RAID configurations-for example, using RAID 0+1-both mirroring and striping-in order to gain the greatest read performance from their hardware without losing redundancy. While RAID 5 provides for redundancy at a byalongshot lower cost, most database vendors today recommend RAID 0+1 for tables as well as logs and only recommend RAID 5 for less performance-critical backup volumes. Caribou Lake's Leo says, "Performance is highly contingent upon how you configure the SAN. They hold seen very kindly performance for databases with RAID 1+0 kind configurations. They hold too seen decent performance for RAID 5, unless the RAID 5 is in rebuild. If the RAID 5 is in rebuild, write performance is so bad, the system may as well live down."
To further optimize access times and data throughput, database administrators hold to too bear confident that tables and logs never share the identical spindles on a disk. John Eisenschmidt, a DBA at the American Association for the Advancement of Science, Washington, D.C., says for his final install of Oracle, "We made confident not to achieve the index tablespaces with the data tablespaces to help read performance, and achieve the archive logs and redo logs in different places to balance write operations." Eisenschmidt manages about 2.5TB on a SAN filesystem on Xiotech hardware, used for storing user files, though he silent runs his databases on raw dedicated disk.
However, with the advent of SANs and virtualized storage, administrators no longer hold that plane of control of data placement. According to Bob Rogers, chief technology officer of BMC Software, "Most DBAs are absolutely convinced that file placement is an absolutely critical issue, however, most disks today are virtualized-and users don't hold a clue where things are physically located."
Luckily, the quicken and manageability of storage hold improved the situation, despite the loss in control. Rogers says, "Today, you can win a much more consistent plane of performance by going to very big arrays such as those from EMC, IBM, and HDS than you could going to direct-attach disk."
Enter virtualizationDespite virtualization's steady march into storage systems, most vendors and users assume that some control is silent needed to fully optimize database access. Oracle's Hoke says, "One of the substantial bad things that can befall with virtualization is that you can hold two tables related in your traffic application, with a tall plane of traffic in inescapable rows of those tables."One way to Dramatically augment Database Performance Question: "Have you reach across some hard numbers and performance figures for the exhaust of RAID (at any level) in the database environment?"Securing PDAs with sensitive data - or access to it - should live taken seriously. Basically, you exigency to apply the identical rigor to PDA security that you would to any other enterprise-class device, with a pellucid security policy and a uniform suite of security software. regard the following:Chris Poelker: Database application performance shouldn't only live looked at from an I/O standpoint, but first and foremost from a design perspective. For example, at one customer site, they were using SQL server in a three-tier Web application, where the Web pages were built dynamically from the database. The design used active server page scripts in the application tier to query the database for results and the results were then sent to the Web server to build the dynamic pages.By pathetic to SQL - stored procedures at the database level, and tuning the indexing methods - and a slight schema redesign-performance improved by over 800%, everything without even touching the back immediate I/O. Never cast hardware at a impecunious design as the revert on investment is never as kindly as taking the time to rethink the original design.Here's the some things to conclude for kindly I/O performance:1) exhaust a lot of spindles. If you proceed to and gaze at the specifications on the designs to achieve maximum database performance, you'll notice they exhaust hundreds of drives. By a lot of spindles, I don't standfor big RAID sets. You should concatenate many smaller RAID sets into a single LUN either by using host software or LUN virtualization within the storage hardware, if it has that capability.2) exhaust low latency paths to storage. Fibre Channel uses a packet-based network, which allows for a plenary duplex backend. On a SCSI bus, only one thing can befall at a time. Using dual-pathed Fibre disks, you can hold a read command on one side and a write command on the other side of the disk being queued at the identical time.3) Spread the I/O load as much as possible. exhaust many HBAs in the server that are load balancing your I/O across everything the paths. Tools love Veritas' Volume Manager or Solstice Disk Suite can aid conclude this by creating a single LUN from many spindles on each path. By using 2Gb paths and four HBAs, you can win immediate to 800MB/sec to the LUN.4) exhaust the proper RAID plane for the log and database. Best practice here is log files should live on RAID 0+1 (RAID 10) and databases on RAID5 (RAID 0+1 can live used on the database for better performance if your budget allows for it).Performance. Today's hard drives can achieve a sustained throughput of between 30MB/s and 50MB/s and 120 to 140 IOPS (I/Os per second) per spindle. The performance depends on the drive electronics, onboard cache size, rotation quicken (15,000 RPM is better than 7,200 RPM of course) and maximum seek latency. If you partition your RAID set into little partitions, and locate your data on the outer cylinders, your performance will proceed up substantially. Doing this reduces the seek time for a particular partition. Now just add up the number of spindles to design out your maximum IOPS. design 1680 IOPS using 14 spindles on one HBA, or 3360 IOPS using 2 HBAs to 28 disks doing 64,000 sequential I/O(random I/O will live less). Changing the screen size of the transfer will either augment MB per second (throughput) or IOPS. Smaller blocks bear IOPS proceed up, larger blocks bear throughput proceed up.These numbers are for direct I/O, sense no cache in front of the drives. Adding cache can augment performance dramatically. I hold seen 33,000 IOPS on a single LUN during 100% cache hit. So, if you want the best I/O performance available, exhaust a solid-state disk.Christopher Poelker is a storage architect at Hitachi Data Systems. He answers readers' questions on "Ask the Expert" at SearchStorage.com.
According to Hoke, a kindly database administrator will try to spread those tables across multiple devices, so he doesn't create hotspots, and too for availability. However, with virtualization, those two tables may live inadvertently placed on the identical disk, because virtualization masks physical locations. "Virtualization is distinguished for provisioning storage because it's facile to prance data and add disks. But with a database, because of performance issues, there are potential drawbacks," Hoke says.
CreekPath's Booth agrees: "File placement is silent absolutely indispensable with a SAN, although disks hold gotten faster. It silent comes down to laying down data on a spinning disk, and not putting redo logs and indexes on the identical physical drives. That's why it's indispensable for tools to espy everything the way down to the spindle level, so that when they're laying down data it's not stepping on its own toes."
Marty Ward, director of product marketing at Veritas concurs, although he doesn't assume administrators exigency to live directly concerned with where data is, "DBAs don't exigency to live considered about which spindle disk data lies on. They capture supervision of that for them. Their logical volumes allow them to prance data around on-the- soar to adjust hotspots, even while running." Other vendors are too announcing tools in this area.
Durnford sees things the identical way. "Using JBOD, you're much more sensitive to placements [hotspots]. However, using storage arrays, they exhaust their technology to prance storage around while running to purge hotspots, so that the server doesn't really exigency to know the physical storage location," he says. Durnford uses built-in tools on his Hitachi, IBM, and EMC arrays to deal with hotspots on his volumes.
SAN issues"In the fragile days of NFS [network file systems], due to lack of availability capabilities for Oracle, their customers saw storage corruption," says Oracle's Hoke. Because of those issues, Oracle's validation program for network-attached storage arose out of concern about the nature of NFS," he says.
In a SAN, storage just looks love a SCSI disk-reducing a number of the headaches that came with putting databases on network-attached storage, since the interface is identical to that of SCSI. Unlike NAS - with storage networks Oracle has left it to their storage partners to qualify HBAs - switches and front-end storage FC adapters. Hoke says that with a SAN, "We hold not identified anything needing validation."
However, it silent takes some work to win SANs performing perquisite for databases. DBA Eisenschmidt - despite running a SAN for his applications and file systems -is skeptical of using SANs for his database storage. "Our SAN, love many I've seen, is optimized for storage capacity and file serving. While Oracle uses Xiotech's Magnitude in their test labs, I was pretty unhappy with the transaction performance they were able to win out of it."
CreekPath's Booth says, "The biggest issue with databases on a SAN is maintaining consistent throughput and access on a database while running other application sharing the identical SAN."
Caribou Lake's Leo agrees, saying, "SANs often reclaim an enterprise money by sharing I/O capacity across departments. But sharing I/O resources between the user files of one department and the DBMS storage for another is awful. The database management system's I/O characteristics are completely different than the user data files, and cache coherency becomes an issue."
Royal Bank of Canada's Durnford has opted for sever storage networks to unravel some of these problems. He says, "For tape, we're looking at a sever tape SAN. The issue there is database traffic is very time-sensitive, where tape traffic is very backup-oriented. Though you might assume it's time shifted, we've institute there's overlap."
The other issue most DBAs mention is the complexity of managing storage networks, which are typically managed by sever storage infrastructure staff. "A lot of progress has been made in the final brace years, but most system administrators want SANs that are easier to administrate. I want a more trustworthy SAN whose caching I'm not apprehensive to whirl on," Eisenshmidt says.
Leo says that when you achieve a database and storage together, "You realize that your SAN management team must work closely with the DBMS team. They hold seen situations where SAN managers hold decided to change the SAN configuration because it seems wasteful or odd, not realizing how carefully tuned the setup was."
CreekPath's Booth too agrees, adage that while heedful tuning of how storage is configured can purge sharing issues, "Both DBAs and storage administrators exigency to live on the identical page."
Despite the issues, some users hold had distinguished success running SANs with their databases. John Brooks, vice president of storage engineering at Cleveland, OH-based National City Bank, runs an 18TB SAN, which is based on Brocade switches with IBM and Hitachi arrays. "We hold no issues with running on a SAN. Not even performance issues. It just seems to run," he says. Asked if he does anything special for databases, he says "For SQL and Oracle databases, they cast it on the SAN." Brooks attributes the lack of issues to the relationship he has with his storage vendors. He says, "We conclude a lot of research, primarily in the interoperability belt that might account for the lack of issues. They work very closely with their storage vendors to ensure certification and supportability of the environment, in case issues conclude arise."
Tools and techniquesBecause SANs' original role as the primary storage for databases, there's now a exigency for improved tools and software to manage the combination of database applications and storage. "It would live nice if vendors could provide some sort of management utensil to track why a SAN partition was configured in a inescapable way, thus preventing the loss of historically significant details when SAN management changes hands," says DBA Leo.
"If I could hold anything from a SAN to bear it better for a database, I'd examine the vendors to write better drivers. Most of the drivers I've seen and worked with just reveal the OS the drive is gone when the SAN disconnects, instead of perhaps telling it to wait or trying to free the process," Eisenshmidt says.
Some vendors seem to live listening and are increasingly focusing their efforts on getting their database to flee better on SANs, and their storage and infrastructure to better back databases. Take, for example, Oracle's Hardware-Assisted Resilient Data (HARD) initiative (see "Oracle's storage push"). Oracle's Hoke explains, "We're working with hardware partners to verify that when Oracle data is transferred to a disk it can live read. This sounds simple, but with storage management and storage virtualization in storage networks, there are lots of cooks in the broth."
Part of Oracle's hard initiative, EMC's Oracle Double Checksum utensil offers the talent to verify Oracle data as it is written to arrays in microcode, ensuring that corrupted data is never written to disk. Competitor Hitachi Data Systems has too announced back for the initiative, with a microcode-based verification of Oracle data in their Lightning 9900V product.
EMC too offers its Symmetrix Optimizer, which makes recommendations to administrators on where to rebalance data-a must for administrators looking for flaming spindles. EMC has a immediate partnership with Oracle, including a dedicated engineering team at Oracle Redwood Shores. Chuck Hollis, EMC's vice president of products and markets says, "We hold 12 to 15 engineers inside Oracle, some dedicated to interoperability, and the comfort to feature exploitation such as their Double Checksum product and integration between Oracle and their replication products."
Veritas too offers a host of products designed to work with databases and SANs. The company's Database Edition products for Oracle9i, IBM DB2, and Microsoft Exchange, including mirroring, backup, replication and clustering features designed for those databases. According to Veritas' Ward, an upcoming release of the company's storage resource management product, "will map data everything the way from a database environment in Oracle or Exchange, through files, everything the way down to disks to note you which spindles and extents the data is written to."
BMC offers its PATROL for Storage Management product. BMC's Rogers says, "When you're working with Oracle or Sybase or Microsoft SQL server and even Exchange, they can expose that from a database perspective. For example; they can expose an Oracle instance that is on a Solaris box and attached to a SAN, and espy where it is spread about. They can expose that through a topology manager-all of the connections, single points of failure, and the way the database is laid out on disk."
Despite complexities of managing databases running on storage networks, the benefits are clear. For big databases, there's really no better option that a SAN because of the plane of performance, consistency, redundancy, and scalability that a storage network provides. Storage and database administrators alike are finding that the only way to back their mission critical applications is to deploy their databases on a storage network. With so much at stake, storage and database vendors will continue to work more in tandem to bear their products work better together (see "Vendor independence: Are the trade-offs worth it?").
This article is the second in a sequence that discusses a policy of security incident responses. The article describes the policy best practices and execution features — evaluation, containment, and eradication of and recovery from a security incident — for responding to a customer's incident within the policy scope.Like this article? They recommend
There hold been several large-scale worm attacks on the Internet since 1988 and highly visible and coordinated denial-of-service attacks in the final few years causing billions of dollars in damage. These attacks indicate that responding to such incidents is increasingly more tangled and requires technical knowledge, communication, and coordination among the staff responding to an incident, along with an adherence to applicable standards and policies.
A security incident response involves several aspects of preventive, detective, and recovery measures. A preventive measure primarily involves risk control that mitigates the effects or deters the incident of an undesirable event. Examples of preventive measures are passwords, keycards, badges, contingency plans, policies, firewalls, and encryption. A detective measure identifies the incident of an undesirable event. Examples of detective measures are visitor logs, audit trails, motion sensors, closed-circuit TV, and security reviews. Detective measures too provide a means for reporting the incident of events. A recovery measure is a risk control that will, in a traditional sense, comprise control policies, processes, or mechanisms that restore the integrity, availability, and confidentiality of information assets to their expected state. Examples of recovery measures are foible tolerance, backup, and cataclysm recovery plans.
Since the late eighties and early nineties, a substantial amount of information has been published on the topic of security incident response from the following organizations:
Australian Computer Emergency Response Team (AusCERT), http://www.auscert.org.au/
Brazil's Centro de Atendimento a Incidents de Segurança (CAIS), http://www.rnp.br/lang/cais_en/
Carnegie Mellon University's Software Engineering Institute's Computer Emergency Response Team/Coordination hub (CERT/CC), which was initiated by the Defense Advanced Research Projects Agency (DARPA), http://www.cert.org
European Institute for Computer Antivirus Research, http://www.eicar.org/
German Computer Emergency Response Team (DFN-CERT), http://www.cert.dfn.de/
Internet Engineering assignment accommodate (IETF) in the form of RFCs, http://www.ietf.org/rfc.html
Purdue University's Computer Incident Advisory Capability (CIAC), which is funded by the Department of Energy, http://www.ciac.org/ciac
SysAdmin, Audit, Network, and Security, http://www.sans.org
U.S.'s National Institute of Standards and Technology (NIST), http://www.nist.gov
In 1990, NIST, in conjunction with CERT/CC, CIAC, NASA, and other agency response teams, organized a cooperative activity known as the Forum of Incident Response and Security Teams (FIRST) at: http://www.first.org
This coalition brings together a variety of computer incident response teams from governments, commercial organizations, and academic organizations. FIRST fosters cooperation and coordination in incident prevention, prompts rapid reaction to incidents, and promotes information sharing and learning among the members of its community.
": Executing a Policy" is the second of a sequence of articles that argue a security incident response policy and execution. These articles are not intended to comprise everything of the material from the above efforts. They are intended to capture the signal points of the security incident response process and to present them in the context of a traffic entity that serves its constituents (that is, its customers).
The first article, "Responding to a Customer's Security Incidents—Part 1: Establishing Teams and a Policy," contains definitions of security incidents, security incident response, teams that typically are involved in an incident response, the pros and cons of the teams, and the scope and goals of the security incident response policy. In addition, it describes policy essentials for the notification aspect of a security incident.
This second article describes the best practices and execution of key policy features of responding to a customer's incident within the policy scope described in the first article. These features mainly comprise evaluation, containment, and eradication of and recovery from a security incident. Subsequent articles will focus on incident follow-up, with a special accent on forensics, risk analysis, cataclysm recovery, and government and legal recourses, as well as proactive teamwork. The primary audience consists of computer security managers, security policy developers, system administrators, and other related staff, answerable for the creation or operation of a computer security incident response policy and service.
