Keep the system and browser current
- Install operating system updates promptly. Updates fix weaknesses that could put saved business sessions, files, and credentials at risk.
- Turn on automatic updates where practical. This reduces the chance that important security fixes are overlooked.
- Update browsers and their extensions. Outdated browser components can expose account activity or interfere with secure sign-ins.
- Remove extensions you no longer need. Each extension may access browsing data, so keep only those that are necessary and trustworthy.
Protect access to the computer
- Use reputable security software and keep it updated. It can help detect malicious files and suspicious activity, though it does not replace careful handling.
- Encrypt the device’s storage. Encryption helps protect business files and saved browser data if the computer is lost or stolen.
- Create a separate user account for work. Keeping work activity apart from personal use helps limit accidental access and makes browser profiles easier to manage.
- Set a strong sign-in method for the work account. A device password or other supported sign-in protection can make casual access more difficult.
- Lock the screen whenever you step away. An unattended, unlocked computer can expose open accounts and confidential information.
Handle software and downloads carefully
- Avoid pirated software and unlicensed copies. They may contain harmful code, lack security updates, or violate the software provider’s terms.
- Download software only from sources you can verify. Familiar, legitimate distribution channels reduce the risk of installing a tampered file.
- Treat unexpected attachments and downloads with caution. A file can look routine while carrying malware or leading to a phishing attempt.
- Scan files before opening them when appropriate. A security check can help flag known threats, but it cannot guarantee that a file is safe.
- Do not grant broad permissions without a clear reason. An application with unnecessary access may reach work files, browsing data, or other sensitive information.
Keep work profiles organised
- Use a dedicated browser profile for each distinct work context. Separate profiles help keep cookies, history, saved sign-ins, and extensions from becoming mixed.
- Give profiles clear, non-sensitive labels. Useful labels make routine selection easier without exposing confidential account details on screen.
- Back up only what the work process requires. Browser profiles can contain active sessions and sensitive data, so store backups securely and restrict access.
- Review who can access or receive a profile backup. A handover should follow the organisation’s access rules and the relevant platform’s terms.
- Use a separate device or isolated profile to test unfamiliar tools. This limits the chance that an untrusted application can access active business sessions or work data.
Retire devices safely
- Sign out of business accounts before handing over a computer. This reduces the chance that the next person can open an existing session.
- Remove work profiles and saved credentials before disposal or reassignment. Browser data can remain sensitive even after visible files have been deleted.
- Erase the device using its supported secure reset process. A proper reset helps prevent the next owner from recovering work information.
- Confirm that required work files are backed up before erasing. A secure handover should protect both confidential data and necessary business records.
- Follow your organisation’s disposal and retention rules. These may require specific handling for devices, storage media, or account access.
