Sometimes, the first a victim knows they have been compromised when Google blacklists their site for serving malware, or their bank queries them about unusual transactions.
Hacking is no longer about curious teenagers, bragging rights
and political “hacktivism”, but is now about money making cyber-crime.
While the first response of most organisations is “I don’t have
anything worth stealing”, what many IT administrators don’t understand
is that cyber criminals can use your website to distribute malicious
software to your visitors – without changing the content on your site.
They can change account numbers in your payroll system, or even add new
employees which can be difficult to detect. They can also sit in
silence with keystroke loggers waiting for someone to connect to a
net-banking site.
Having an intrusion prevention system can stop known attacks,
and often can give warning of zero day attacks (As hosts are usually
scanned for vulnerabilities before exploits are attempted). Breaking
into a site with a well maintained intrusion prevention system is
beyond the skill of most hackers – including experienced penetration
testers.
However, installing an Intrusion Prevention system is not
quite as simple as plugging it in and turning it on. Poorly configured
Intrusion Prevention systems slow network access, stop legitimate
traffic and create endless alarms.
With over a years of experience performing legal intrusions
(penetration testing) and building and tuning intrusion prevention
systems, ISCS can offer your organisation a very effective defence that
requires minimum maintenance, while providing you reports that show
where the threats are coming from, and what they’are trying to get to.
This can provide you strategic information to better secure your
network in the long run.
Fill out our contact form to get an
obligation free, four week trial of an intrusion detection device (the
trial will not block traffic, minimising the risk of false blocking),
with comprehensive reports at the end showing how your network could be
better protected.
