Purpose

51直播鈥檚 customers are dependent on our services operating as normal. Proper detection and response to incidents that may impact the integrity, confidentiality or availability of services and data is critical to the operation of 51直播.

Scope

The following minimum standards apply to 51直播鈥檚 assets as managed by employees, contractors and vendors. These recommendations represent the recommended minimum efforts necessary for incident detection and response.

Policy

Incident detection

An incident could be detected by automated alerting, internally by an employee in their course of work, by an employee or vendor doing a review of 51直播鈥檚 security posture, or an external third party reporting a potential vulnerability to us.

If you see something, say something. All 51直播 employees must immediately report suspected security incidents or suspicious activity that occurs at 51直播, including but not limited to security incidents, physical injury, theft, property damage, denial of service attacks, threats, harassment, abuse of individual user accounts, forgery and misrepresentation. Suspicious activity can be reported to the Slack channel #incident-response, or, for potentially sensitive incidents, to the Security Review Team or to the Chief Operating Officer (COO). Violations of the must be reported to the Chief Operating Officer (COO).

All employees much watch for potentially suspicious activities, including:

• Warnings from antivirus tools
• Unexpected system reboots and/or sudden degradation of system performance
• Password reset notifications
• Modification or defacement of websites
• New open network ports on a system
• Multi-factor authentication prompts

51直播 regularly reviews logs to detect and track attempted intrusions and other suspicious activity. These include git, cloud, networking, SaaS tools, and other infrastructure logs.

The Security Review Team:

• Ensures that a very high level of logging is enabled
• Checks logs regularly for suspicious activities and entries
