Firewalls & Security
Are you secure?
We've had our share of attempted hacks by our competitors - in one instance where we displaced an IT company who weren't too happy and started a DoS attack, we set up the necessary trace during their attack to present their MD with the evidence and a polite invitation to stop or have a visit from his local constabulary.
In short, to keep ahead of the game, we've become gamekeepers turned poachers including a server installed in our datacentre loaded with some "interesting software" capable of exploiting even the slightest security flaw which we frequently use to test our own installations.
Security is one of those topics that requires individual environmental analysis, but as an overview:
Router:
All DSL lines installed by us use
ICSA certified router. This keeps moderate attempts and "drive-by" probes at bay.
Dedicated firewall:
We then also install a second dedicated firewall "in series". We have worked with Zyxell® for a number of years. They are one of only 2 vendors whose firewalls are capable of the highest Layer 7 (OSI) packet inspection - thwarting file transfers over the ever rising popularity of Instant Messaging.
CISCO IDP:
We've invested in CISCO's IDP which monitors and terminates any dubious sessions attempted from outside our private ISP cloud;
Email Protection:
Stop emails that carry malware payloads and enticements to click on web-sites using
IntraLAN's Email Protection services;
Manage web-site access:
Content Filtering to disable access to any web-sites except xyz, or allow access to all web-sites except specified genre (porn, gambling, social etc);
Lock-down VPN permissions:
Locking down remote site access to head offices (so only known VPNs are allowed in);
SSL certificates:
SSL certificated connetions are also supporte by the Zywall routers.
Each site will use a different combination of tools from the example above. There are more - if you would like ot discuss a particular requirement, please contact us.
