Whether it’s mildly irritating offers for cut-price blue pills, or something altogether more sinister such as holding your company files ransom, today’s cyber-criminals are using increasingly sophisticated and varied techniques to target your business by email.
Today saw the latest major release of SecurityGateway, a software firewall that sits between your Exchange, MDaemon, Kerio or Smartermail server, and your router, protecting your organisation from spam, viruses, spoofing, phishing and more.
In this post, we take a whistle-stop tour of the new features.
This year in particular, I’ve seen an increasing number of users’ email account credentials become compromised, which has allowed spammers free reign to use their mail server to send spam out to the Internet.
The usual result is an overflowing outbound mail queue, thousands of bounce messages coming in and your server’s IP address being blacklisted.
The first thing to note is that if your company has an email server, you should assume that spammers will always be trying to hijack users’ accounts by guessing their passwords.
In this post I will run through a few simple pro-active settings checks that can reduce the chances of this happening and – in the unfortunate event that it does happen – can limit the resulting negative effects.
Independent analyst and security director for EncSec, Graeme Batsman has appeared in, and advised, publications including SC Magazine, The Independent, Microsoft, Metro, Experian and many more.
Graeme had recently been testing a number of email security products including those from vendors such as Barracuda and Sophos when we contacted him about ‘hot off the press’ SecurityGateway version 3.0.
