Threatcon - Symantec Corp.

The ThreatCon is currently at Level 1: Normal.

The ThreatCon is at Level 1. On June 9, 2009, Microsoft released ten Security Bulletins.
Six of the bulletins are rated 'Critical'. Successful exploitation of the issues discussed in these bulletins may allow remote attackers to execute arbitrary code. The affected software includes Active Directory, Internet Explorer, Word, Excel, Print Spooler, and Works Converters.

Three bulletins that have an 'Important' impact deal with vulnerabilities that may lead to successful privilege escalation. One bulletin with a 'Moderate' impact discusses a vulnerability that may lead to information disclosure.

We are currently not seeing any widespread activity targeting these issues. Patches have been available from Microsoft since Tuesday, June 9, 2009.

Microsoft Security Bulletin Summary for June, 2009
http://www.microsoft.com/technet/security/bulletin/ms09-jun.mspx

ThreatCon Level 1
Low : Basic network posture
This condition applies when there is no discernible network incident activity and no malicious code activity with a moderate or severe risk rating. Under these conditions, only a routine security posture, designed to defeat normal network threats, is warranted. Automated systems and alerting mechanisms should be used.

ThreatCon Level 2
Medium : Increased alertness
This condition applies when knowledge or the expectation of attack activity is present, without specific events occurring or when malicious code reaches a moderate risk rating. Under this condition, a careful examination of vulnerable and exposed systems is appropriate, security applications should be updated with new signatures and/or rules as soon as they become available and careful monitoring of logs is recommended. Changes to the security infrastructure are not required.

ThreatCon Level 3
High : Known threat
This condition applies when an isolated threat to the computing infrastructure is currently underway or when malicious code reaches a severe risk rating. Under this condition, increased monitoring is necessary, security applications should be updated with new signatures and/or rules as soon as they become available and redeployment and reconfiguration of security systems is recommended. People should be able to maintain this posture for a few weeks at a time, as threats come and go.

ThreatCon Level 4
Extreme : Full alert
This condition applies when extreme global network incident activity is in progress. Implementation of measures in this Threat Condition for more than a short period probably will create hardship and affect the normal operations of network infrastructure.
