A business hires two security guards to protect the premises. The first guard patrols the perimeter while the second protects the lobby.
Late one night, the guard patrolling the perimeter discovers a freshly broken window. You’d expect that he would immediately alert the inside security guard about the possibility of an intruder, right?
Unfortunately, IT security doesn’t always apply the same “real-world” logic.
Endpoint security technology detects malware infections and other harmful intrusions. Firewalls regulate network traffic. Some companies use security information and event management (SIEM) to aggregate log data from endpoint and firewall systems, but real-time coordination between the two has not been readily available to most enterprises.
Deploying a Coordinated Defense
One solution that’s available to meet this need is Sophos Security Heartbeat, which allows endpoint security and firewalls to actively communicate every 15 seconds.
Endpoint security shares information on all sensed threats, allowing the firewall to instantly isolate those threats and protect the rest of the network. Conversely, when the firewall detects anomalous traffic, it can isolate any breached endpoints and trigger appropriate action.
Such coordination is key as cyberthreats become more sophisticated. Intruders compromise endpoints in subtle ways that may avoid detection, while continuing to probe the network.
If the endpoint and firewall operate in isolation, they cannot properly respond to this kind of compromise in a timely manner. When those two security pieces work together on even the smallest network traffic anomalies, they help organizations to better protect their overall environment.
Security component coordination offers several benefits.
The first, obviously, is improved security. Endpoint security and firewalls won’t always detect threats when working independently. They also struggle to automatically isolate and neutralize those threats or identify their nature.
For example, a firewall might identify the IP address sending anomalous traffic but not pinpoint the particular user, application or file that is the root cause.
A second benefit might easily be overlooked: Saved time.
IT organizations typically struggle with limited staff budgets. It is wasteful then for employees to spend time remediating small but potentially damaging security events if that pulls them away from more strategic tasks. Automation and real-time security insight can handle that remediation, freeing people to focus more on big-picture initiatives.
Security Heartbeat technology is just part of what makes Sophos a great security partner. With millions of endpoints under protection, Sophos constantly gathers intelligence on the latest cyberthreats against businesses. That broad-based learning benefits every Sophos site because it enables the company’s technology to better detect digital behavior that may be symptomatic of an active exploit.
