This week was dominated by another big buy for HP, this time the $1.5bn deal for ArcSight. Elsewhere, Adobe disclosed more vulnerabilities in Flash Player, and IBM released its first Guardium products under the InfoSphere brand.
First up, it emerged that the recent outbreak of an email worm is the work of a hacker group opposing US involvement in the Middle East.
SecureWorks said that the fast-moving 'Here You Are' malware was created by 'Brigades of Tariq ibn Ziyad', a group described as a 'cyber-jihad' organisation whose goals include infiltrating US government and military systems.
It was another bad week for Adobe, after the firm was forced to acknowledge another critical hole in its popular Flash Player software, which is already being exploited in the wild and could allow an attacker to take control of an affected system.
The news follows the discovery of critical vulnerabilities in Adobe's Reader and Acrobat applications just last week.
Elsewhere, AVG warned users of social networks to be on their guard after new research uncovered over 20,000 compromised web pages belonging to the top 50 such sites.
The security firm analysed the sites through its AVG Threat Labs online web scanning tool. Unsurprisingly, it found that 11,701 of the 19,491 compromised web pages are on the world's largest social network, Facebook.
Meanwhile, McAfee warned that people searching for free music are laying themselves open to ma lware attacks.
Also this week, IBM released InfoSphere Guardium 8, designed to automatically monitor application and data use, and alert administrators about any unusual or non-compliant activity.
InfoSphere Guardium can help firms tackle insider and outsider threats, according to IBM, and limit the risk associated with data breaches.
New resesarch from PricewaterhouseCoopers revealed that UK companies are seriously lagging behind their international rivals when it comes to planned spending on information security.

Information security certifications organisation ISC2 has launched a professional networking site designed to give its 70,000 members a forum to discuss the latest security and careers trends. InterSeC currently has more than 8,500 professionals participating on the site.
And finally, the big story of the week was HP's $1.5bn (£973m) deal to acquire ArcSight. ArcSight sells security systems pitched at big-spending organisations including governments and enterprises.
The software includes tools to protect against cyber theft, fraud, warfare and espionage, as well as ensuring regulatory compliance.
Tom Reilly, president and chief executive of ArcSight, said in a statement that the acquisition will enable the creation of "a new type of security solut ion" designed to serve the modern enterprise.
