Other Comments for consideration

As examples, following items are not in the current objectives:

1) Related to Wireless LAN: (Note: It’s not only for Linux though, it is necessary to consider because there are many points to be taken care for configuration in terms of security measure.)

Some aspects (i.e. Radius) are implemented in V2 (fth)

2) Related to IPv6: Not only IPv4, but also IPv6 should be considered.

Implemented in V2 wherever applicable (fth)

3) Security features in Linux: For example, ASLR and Exec-Shield (ASCII Armor) should be considered, because it causes security level lower if those are disabled.

Implemented in host hardening in V2 (fth)

4) Related to Forensics: In the survey of malware’s behavior, Sleuth Kit would be used to analyze the hard disk on Linux machine. Also in some cases, LVM commands would be used to restore the disk which became un-mountable. So that this area should be learned.

This is an interesting topic, but it goes beyond basic security in the sense it "prevention and defending". This is postmortal analysis. As the exam already contains a lot of topic this is postponed but up to discussion (fth)

5) Database (RDB, NoSQL) security: Because Application Security (bind, apache, etc.) is covered now, this item would be nice to cover. And this item is listed in the CIF, security contest almost every time. Also the counter-measure in server side is necessary.

As the other software / service aspects beyond Linux system security have been dropped this is considered out of scope for now too (fth)

6) Related to OpenFlow: There are several points to be considered in terms of security measure about the configuration of OpenFlow.

This is considered as an application aspect which seems to be beyond the scope for not (fth).

7) RADIUS: This was covered in 301 though, this is not covered now. This should be covered.

Implemented in V2 (fth)

8) DNS: More DNSSEC and DANE.

Implemented in V2 (fth)

9) Secure development, hardening

Hardening has been implemented for both hosts and networks in V2 (fth), Secure development is considered out of scope for now (fth)

10) Certificate Transparency
