The consequences of any of your company's information being lost or inadvertently disclosed, or your computer network becoming infected by viruses, would be significant. Enormous damage could be done to your business and your reputation.
Effective computer security is crucial. Everyone in your organization is responsible for anything carried out under your accounts. We are all expected to act as the first line of defense and adopt a culture of awareness of information security threats.
Keeping Your Computer Safe
Using computers securely is a vital part of your IT and information security approach and supports your overall business growth. Here are some suggested best practices for your organization:
- Keep your passwords secret
- Delete files that you no longer need and make sure you empty your deleted items folder or recycle bin
- Do not let anyone else use your computer and always lock it when you leave your desk; use 'Ctrl + Alt + Delete' then 'Lock', or 'Windows key + L', to lock your screen
- Log off and shut down your computer at the end of every working day
- Not leave your laptop in view in your office overnight – lock it away or take it home
If you think your computer might have been tampered with, immediately report it to your local Security Lead in your company.
Acceptable Computer Use
- Make sure that your computer is only used for business purposes
- Keep the storage of personal files to a minimum, for example photographs and music files, as these take up valuable space in company storage and can slow down the system
- Get the approval of the Information Owner, and your Legal Department if necessary, before publishing or sending any sensitive information
Make sure to never:
- Download, store, send or distribute offensive or pornographic content, or any other content that could damage your company’s reputation
- Conduct a private business using your equipment
- Delete or alter any of your company’s information without permission
- Use your computers to improperly copy, store or disseminate copyrighted or licensed materials
- Connect any non-company device to the network without business justification and the approval of your manager and local Security Lead
Computer Software and Maintenance
Using unauthorized software, or modifying computer security settings, could lead to virus infections or network malfunctions. Be sure only your IT staff installs, configures, maintains, repairs or removes your computers or systems.
Be sure not to:
- Modify the operating system or configuration of workstations
- Ignore, disable or remove system security controls such as antivirus software or firewalls
- Copy our licensed software to non-company hardware
As another level of security, be sure not install or use any of the following on your equipment:
- Any type of unauthorized, unlicensed, free, privately written or gaming software or software from non-professional or untrusted sources
- Unlicensed copies of authorized software
- Password cracking software
- Offensive, pirated or illegally copied videos
- Any software that might endanger network security or provide unauthorized access
Whether you’re a multi-national corporation, mid-size company or a local business, following the above-mentioned best practices will keep your computer and company’s vital information better secured. If in doubt, always contact your local IT team.
