Computer Network Security
Computer network security is a complex subject and is never just a single solution. It requires a layered approach using staff training, security best practices and security products to protect the different aspects of a network. The only way to be completely secure is to isolate the system from any networks, including the Internet, which is not practical. It is impossible to make any system entirely safe while still being useful. Therefore a considered approach balancing functionality against cost and inconvenience is required to reduce the risks to the absolute minimum.
Malware is a blanket term to cover all types of malicious software. There are many categories of malware, and they vary from simple programs that are a bit of fun up to ransomware which encrypts your files and demands a ransom paid in bitcoin for the encryption key. Ransomware is the most worrying development in the criminal exploitation of decent people and paying the ransom is no guarantee of regaining your data. It is impossible to trace criminals who you have paid with Bitcoin.
Protection against all forms of malware requires a layered approach. Always filter E-mail through anti-spam and anti-virus systems. Install Good quality antivirus software on all computers and servers as well as Android-based phones and tablets.
Apple phones and tablets don’t currently have anti-virus products because Apple tightly controls apps installed from the Apple store. Jailbroken IOS devices are more vulnerable, so they should be avoided.
Many Apple computer users think Apple computers can’t get viruses which is not the case, and because of the increasing user base criminals are increasingly targeting Apple products.
All systems should have the latest security patches installed regularly to protect against known threats.
Regular data backups ensure you can recover your data when any form of disaster strikes.
