What a nightmare of a 2 weeks! At work we got hit big time by Malware. Got a little too cosy thinking our Anti-Virus protection software would keep us safe. If I have two pieces of advice after spending 2 weeks getting out Sri Lanka network back to normal they would be.
- Ensure all your windows Operating Systems have the latest service pack and have all the critical patches installed.
- Ensure all your windows Operating Systems have the latest service pack and have all the critical patches installed.
Without them you are a sitting duck.
I had a couple of 24 sessions trying to sort things out and learnt more about network security in the last 2 weeks than I had in the previous 5 years.
For the record we use Trend as our anti-virus software and I have to say it falls well short of what I expect of an anti-virus solution. Matters weren't helped when Keytech, the company responsible for managing our firewall somehow managed to leave port 80 open after an IP address range change.
