Introduction.
Although every new year brings with it new network technologies it also, sadly, brings new challenges in the fight to maintain the security of computer networks. The rapidity with which both the networking technology and the threats to it can change means that the idea of having a completely protected network is redundant. However, that is not to say that you cannot have robust and cost-effective network security systems.
Seek, find and destroy.
Ask any of the professional and reputable IT consultancy companies in Hong Kong and they will all state that your ability to be ever vigilant for attacks on your network, and then finding them and eradicating them, is simply the best line of defense. Apart from firewalls and anti-virus protection, or static protection, this means employing the very best in proactive protection in the security and design of your network. Depending on your economies of scale you might want to consider IT outsourcing this aspect of systems design and implementations. This is invariably more cost-effective than trying to train and then retain your own staff across several sites/installations.
People are a risk too!
All too easy and all too often overlooked is the security threat your staff can place your network under. Leaving aside any malicious acts by your staff deliberately stealing or sabotaging data, just what exactly are they bringing in on their works laptops or memory sticks; let alone any personal devices they might be using to work on data away from the office? This means that apart from security threats arising from data received via the internet every data input/output interface on your network is a potentially weak point. The answer to this problem is to have a Hong Kong IT services company assess the threat of such possibilities and then install the necessary barriers to protect the network. This can be something as simple as adding a network routine that automatically scans memory sticks as soon as they’re inserted in a USB port; to only allowing ‘recognized’ devices being able to be connected anyway.
Have a plan.
To protect your network you need a plan and the following provides an outline for you to adopt. First of all having proxy caching, anti-virus and a firewall are basic essentials for even basic home IT security. However, for your business why not add a second firewall, with both firewalls being obtained from separate vendors. That way if you are subject to an attack there’ll be two different defenses needing breaching and the chances are - the attacker will go away and try and find something easier to hack into. Don’t allow any ‘dial-in’ access to your corporate network; only allow remote access through a VPN (virtual private network) set up by your IT support provider. As well as having intrusion detection and prevention systems use network server support to monitor and log any threats and their responses. However, that in itself is not enough as you need to do something with the information gathered; so make sure part of your systems solutions is to have access to trained computer security analysts to act on the computer forensics uncovered. Finally do consider how vulnerable you might be to a complete denial of service attack, rendering your company’s network inoperable and costing you money by the minute. A top quality Hong Kong based IT company like Dual Layer Systems Solutions can advise you how you can protect your network even against something as potentially disruptive as a denial of service.
