A New Year’s resolution is a commitment that a person makes to one or more personal goals, projects, or the reforming of a habit.
- The ancient Babylonians made promises to their gods at the start of each year that they would return borrowed objects and pay their debts.
- The Romans began each year by making promises to the god Janus, for whom the month of January is named.
- In the Medieval era, the knights took the “peacock vow” at the end of the Christmas season each year to re-affirm their commitment to chivalry.
Here are mine:
1) Shed those extra pounds of logs:
Log retention is always a challenge — how much to keep, for how long? Keep them too long and they are just eating away storage space. Pitch them mercilessly and keep wondering if you will need them. For guidance, look to any regulation that may apply. PCI-DSS says 365 days, for example; NIST 800-92 unhelpfully says “This should be driven primarily by organizational policies” and then goes on to classify logs into system, infrastructure and application levels. Bottom line, use your judgment because you know your environment best.
2) Exercise your log analysis muscles regularly
As the Verizon Data Breach report says year in and year out, the bad guys are hoping that you are not collecting logs, and if you are, that you are not reviewing them. More than 96% of all attacks were not highly difficult and were avoidable (at least in hindsight) without difficult or expensive countermeasures. Easier said than done, isn’t it? Consider co-sourcing the effort.
3) Play with existing toys before buying new ones
Know what configuration assessment is? It’s applying secure configurations to existing equipment. Agencies such as NIST, CIS and DISA provide detailed guidelines. Vendors such as Microsoft provide hardening guides. It’s a question of applying them to existing hardware. This reduces attack surface and contributes greatly to a more secure posture. You already have the equipment, just apply the secure configuration. EventTracker can help measure results.
Happy New Year.
