LINUX ESSENTIALS AND ADMINISTRATION
Security
- Configure
and use system log files to meet administrative and security needs
- Setup
user level security
- Configure
security environment files (for example: hosts.allow, sudoers, ftpusers, sshd_config,
PAM)
- Set
up secure shell (OpenSSH)
- Delete
accounts while maintaining data stored in that user's home directory
- Given
security requirements, implement appropriate encryption configuration (for example:
blowfish 3DES, MD5)
- Detect
symptoms that indicate a machine's security has been compromised (for example:
review logfiles for irregularities or intrusion attempts)
- Use
appropriate access level for login (for example: root level vs user level activities,
su, sudo)
- Set
process and special permissions (for example: SUID, GUID)
- Identify
different Linux Intrusion Detection Systems (IDS) (for example: Snort, PortSentry)
- Given
security requirements, implement basic IP tables/chains (note: requires knowledge
of common ports)
- Implement
security auditing for files and authentication
- Identify
whether a package or file has been corrupted / altered (for example: checksum,
Tripwire)
- Given
a set of security requirements, set password policies to match (complexity / aging
/ shadowed passwords) (for example: identify systems not shadow passwords)
- Identify
security vulnerabilities within Linux services
- Set up user-level security (for example: limits on logins, memory usage and processes)
