Based on the feedback you get from your clients, are there more internal or external security breaches?
As outline above, the nature of the modern threat is such that it's really difficult to distinguish between external and internal threats; an external threat can quickly become an internal threat if the multiple edges and access points to business critical data are not 'redoubted' or protected by multiple layers, and internal threats can quickly become external liabilities if your network becomes vulnerable to an agent attack that uses a FTP engine to export internal documents and data, as with the Sasser attack, or uses it's own SMTP engine to harvest internal Outlook accounts and broadcast email spam attacks to the outside world, effectively diminishing your corporate reputation and brand equity. A full context security solution that scans the complete cross-section of internal and external threats is the best way to redoubt network connections.
What do you expect from the future? Is it likely for a "cyberterrorism" event to take place in the next 12 months or do you see it as media hype?
Companies and organisations are victims of a form of cyberterrorism everyday; professional hackers who invade corporate networks to slow down business performance or outright disrupt business continuity are stealing money and damaging reputations. In worse cases, the hackers cause billions of dollars of damage to computer systems or steal sensitive business or customer data. The criminal nature of the blended threat attack is evidenced by the recent arrest of the Sasser attack author.
Cyberterrorism for geopolitical reasons is still and always will be a national security threat that Homeland Security and others rightfully devote major resources to defending against. But organisations and companies of all sizes that are vulnerable to the everyday cyberterrorist's indiscriminate attacks need to take appropriate measures too to shore up their networks and seal off the threat of malicious attacks.
