Other Comments for consideration

Secure development, hardening

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.)

2) Related to IPv6:

Not only IPv4, but also IPv6 should be considered.

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.

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.

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.

6) Related to OpenFlow:

There are several points to be considered in terms of security measure about

the configuration of OpenFlow.

7) RADIUS

This was covered in 301 though, this is not covered now.

This should be covered.

8) DNS

More DNSSEC and DANE.
