Anti-Virus and Malware Policy

Anti-Virus and Malware Policy

Overview & Purpose

The purpose of this policy is to establish guidelines for the prevention, detection, and remediation of viruses, malware, and other malicious software (malware) across [Company Name]'s network and systems. This policy aims to protect [Company Name]'s systems, data, and users from security threats that can compromise the confidentiality, integrity, and availability of company resources.

Scope

This policy applies to all employees, contractors, and third-party vendors who use or manage [Company Name]'s IT systems, devices, and networks. It covers all systems, including desktops, laptops, mobile devices, and servers, as well as any software that can be used to detect and mitigate viruses and malware.

Policy

1. Anti-Virus Software Requirements
   • Installation and Deployment: All devices used to access [Company Name]’s network or systems, including company-issued devices and personal devices used for work (BYOD), must have approved anti-virus software installed.
   • Approved Software: Only anti-virus software approved by [Company Name]'s IT department may be used. The software must be capable of detecting, blocking, and removing viruses, malware, and other security threats.
   • Automatic Updates: Anti-virus software must be configured to receive and apply updates automatically. Definitions and program updates must be installed within 24 hours of release to ensure the software remains effective against the latest threats.
2. Malware Scanning and Detection
   • Real-Time Scanning: Anti-virus software must be configured to perform real-time scanning of files, email attachments, downloads, and web traffic to detect and block malicious content before it can infect systems.
   • Manual Scanning: Employees must be instructed to periodically perform manual scans of their devices, especially if they suspect that a device may be infected with malware.
   • File Integrity Checks: Anti-virus software should periodically verify file integrity to detect changes made by malware, such as file modification or unexpected file creation.
3. Malware Remediation
   • Isolation of Infected Systems: If a device is suspected of being infected with malware, it must be immediately disconnected from the network to prevent further spread. The IT department must investigate and address the infection as soon as possible.
   • Malware Removal: Once malware is detected, the anti-virus software should be used to quarantine or remove the infected files. If the malware cannot be removed automatically, IT support must manually clean or restore the affected system from a known clean backup.
   • System Restoration: If an infection cannot be resolved or if data integrity is compromised, the affected system should be restored from a clean backup taken prior to the infection. Restoration should be performed by IT personnel in coordination with security teams.
4. Security Patching and Updates
   • Timely Patches: All systems must be kept up-to-date with the latest security patches for both operating systems and installed software. Unpatched systems are more vulnerable to exploitation by malware.
   • Critical Vulnerabilities: Security patches for critical vulnerabilities should be applied within 48 hours of release to mitigate the risk of malware exploiting unpatched flaws.
5. Email Security
   • Email Filtering: All incoming emails, including attachments and links, must be scanned for malware by the anti-virus software and email security gateway before being delivered to the recipient.
   • Suspicious Attachments or Links: Employees should be instructed to never open attachments or click on links from unknown or suspicious email senders. Anti-virus software should block suspicious files and links automatically.
   • Phishing Awareness: Employees must receive training on how to recognize phishing attempts, which are often used as a vector for malware infection.
6. Endpoint Protection
   • Endpoint Security: In addition to anti-virus software, endpoint protection solutions (e.g., firewalls, intrusion prevention systems, application whitelisting) should be deployed on all devices to add layers of defense against malware.
   • Mobile Devices: Mobile devices, including smartphones and tablets, must also be protected by anti-virus software or mobile device management (MDM) solutions to prevent malware infection and secure company data.
7. Remote and Cloud-Based Systems
   • Remote Access Security: Devices accessing company systems remotely must have up-to-date anti-virus software installed and configured to scan for malware before they are granted access to [Company Name]’s network.
   • Cloud Services: Cloud-based systems must use advanced malware detection and filtering services to ensure that any files uploaded to or downloaded from cloud storage are free from malware.
8. Incident Reporting and Response
   • Reporting Suspected Infections: Employees must immediately report suspected infections or unusual behavior on their devices to the IT department. All malware incidents must be documented and tracked for follow-up and remediation.
   • Incident Response Plan: In the event of a widespread malware outbreak, the IT department must follow the company’s Incident Response Policy to mitigate the impact, restore systems, and prevent future infections.
9. Employee Awareness and Training
   • Training: All employees must receive training on the importance of anti-virus protection and safe computing practices, including identifying suspicious emails, safe web browsing, and proper use of company-issued devices.
   • Ongoing Awareness: Regular refresher training and awareness campaigns should be conducted to ensure that employees are up-to-date on the latest malware threats and prevention methods.

Compliance

All employees, contractors, and vendors are required to comply with this policy. Failure to adhere to this policy may result in disciplinary action, including termination. Exceptions to this policy must be approved in writing by the Security or Executive team.
