Very timely counsel you offered that companies must take a holistic approach to protecting computer networks from cyber attacks with firewalls, patches and restricted access as key safeguards (“A Web of Attacks,” San Diego Business Journal, Sept. 6).

But it’s important to add a new prevention tool recently developed to detect potential attacks on the network itself as a front-line defense instead of just fighting cyber-attacks at the computer end.

Worms and viruses don’t appear overnight. Hackers initially trial viruses online to test for vulnerabilities. Network engineers can detect such early virus introductions on the Internet through sophisticated monitoring tools, allowing them to block ports targeted by a worm or virus well before a threat exists.

AT & T;’s global Internet network carries enough data each day to fill about 26 million four-drawer filing cabinets. Based on what we see on our network, we can alert our team of security analysts when irregularities appear.

We’ve entered a new era of cyber-security, where a multi-faceted strategy and emerging technologies based on early detection and prevention are essential to protect businesses’ most critical systems against cyber-attacks.
