Managed SIEM: Homeland Security for business networks

December 10, 2015 Arctic Wolf Networks

Hackers will typically not shy away from a challenge, even it if means taking on national government agencies. If the recent data breach against the U.S. Office of Personnel Management that affected more than 20 million federal employees did not make this abundantly clear, then perhaps the recent flurry of government-related cyberattacks will. 

The 2015 United Nations Climate Change Conference, which started on Nov. 30 and will run until Dec. 11 in Paris, was among the most recent targets of notorious hacking group Anonymous. Login information of more than 1,000 officials attending the U.N. event was leaked in response to the arrests of protestors at a peaceful climate protest, according to The Guardian.

Meanwhile, cybercriminals were also hard at work in the Land Down Under. A breach of Australia's Bureau of Meteorology, which houses one of the country's most sophisticated computers, became the victim of a cyberbreach that may have resulted in national security information being compromised, according to Business Insider. At present, China is the number one suspect. Incidentally, that nation and the U.S. just announced a cybersecurity agreement that would improve cooperation in efforts to fight cybercrime. 

The takeaways from these events are twofold. Firstly, no organization is too big to fall prey to a cyberattack, and secondly, preventative cybersecurity by itself simply won't cut it. 

Policing business networks

Think of preventative cybersecurity as a nation's military. In theory, the ultimate goal of the military is to protect the country's residents from foreign threats. This is fine and well, however, there will always be cases in which malicious actors sneak through perimeter checkpoints. This is where U.S. Homeland Security takes over. Federal, state and local law enforcement groups help defend against threats that may dwell within a nation's borders. 

When it comes to the networks of enterprises, small and medium-sized businesses and other organizations, there is too often a lack of layered security that is capable of detecting threats that have already bypassed perimeter defenses. This approach to cybersecurity is the equivalent of a nation that is well-protected against foreign threats, but is completely vulnerable to any hazard within its own borders. As the bevy of recent breaches on government organizations has shown, it's not a question of if, but when – and to what extent – a cyberattack will occur. This is precisely why detective defenses such as managed SIEM services are so essential in modern cybersecurity.

Managed SIEM services closely monitor business networks for unusual traffic, and streamlines the process by which these threats are addressed. Talented cybersecurity specialists man the helm, so that in-house IT staff can worry about fortifying perimeter defenses and managing the myriad other technology resources that are needed to maximize productivity and collaboration among employees. This ensures that highly-trained outside personnel are monitoring the network, and that internal teams can focus on other key matters within their scope.

Managed SIEM is as affordable as it is effective

The ability to monitor network traffic helps companies defend against threats that may have already snuck past the gates. SIEM services can also mitigate damage that may result from shadow IT or generic phishing scams.

That said, traditional SIEM services are often somewhat expensive and difficult to deploy, sometimes taking as long as six to 12 months to launch. Of course, by not leveraging SIEM services, a business would have been taking a huge gamble. Should hackers get into the system undetected, they could take their sweet time pilfering sensitive data. The situation called for a solution that had all the benefits of SIEM services without the hassle. 

"Managed SIEM is effective, affordable and entirely necessary."

Enter, SIEM as a Service, a cloud-based offering that can be launched much more quickly and far more affordably than legacy solutions. It is ideal for businesses with a few hundred employees, or a few thousand. More importantly, it essentially polices the network, much in the same way that Homeland Security protects the people within its borders. 

Managed SIEM is effective, affordable and entirely necessary. Given the urgency of the cyberthreat landscape, there is no longer an excuse for not deploying detective defenses, as they could mean the difference between a close call and a crippling cyberattack.
