When seeking out a competent and professional IT security solution, it’s important to understand the differences between Internet Security, Network Security, and Computer Security an know what your needs are in each area.
Furthermore, many companies providing one type of security well may be completely inadequate in the other areas.
Let’s start by looking at them one at a time:
- Internet Security
- Network Security
- Computer Security
Internet Security
It is easy to confuse Internet Security with Network Security because there is a certain amount of overlap between them. Looking at things that are primarily Internet Security you find issues such as:
- Disclosures from Domain Name registration
- Vulnerabilities to Domain Name Resolution attacks
- Vulnerabilities to Man-in-the-middle attacks
- Weak external routers
- Failure to consider or properly implement a DMZ
- Firewall failures
- Internet Server vulnerabilities
For more detail on these Internet Security issues, check out the Network Security Technology web site or talk to someone at Access Technologies.
Network Security
As stated above, there is a certain overlap between Network Security and Internet Security and it’s important to know how these two issues interplay to affect security.
When considering Network Security, it’s common to consider things that are already inside your firewall. You will typically want one network, or subnet for your DMZ and then one or more internal networks or subnets.
Important issues concerning Network Security include:
- Network traffic control inside the network and traffic going our through or to the DMZ.
- Traffic monitoring for suspicious data packets
- Firewall designs and reviews
- Wireless Network Access Points
- Wireless Security
- Mobile devices such as flash drives, phones, laptops and handheld computers.
As one can see, Network Security is not a simple or unimportant aspect, but is rife with risk. For further information on Network Security including some interesting case studies, go to the Network Security Technology website. For assistance in designing and implementing a reliable Network Security policy, contact Access Technologies.
Computer Security
The issue of Computer Security is as important as any of the rest of the issues. Having computers inside your network that are infected with viruses and Trojan Horses renders all the rest of your security ineffective.
Important things to watch for when considering your Computer Security include:
- Computer Security training
- Up to date and effective virus software
- Security Audits
- Flash Drives
- Save Internet Browsing
- Email and spam filtering
- Choosing a safe Operating System and platform
