Improve Threat Detection and Response with SIEM technology

by Josh Biggs in Tech on 4th September 2021

280 days. That was an average time to identify and contain a breach in 2020. Too much, isn’t it? And business loses money each of these 280 days. Therefore, in order to withstand an attack, it is critical for a business to see and deal with it as soon as possible to prevent irreparable damage. Having a Security Information and Event Management (SIEM) in place you will be able to detect and investigate security incidents, meet compliance requirements and protect your business around the clock. Have security operations services (SOC services) to get more value from SIEM. Geta security team for unstoppable monitoring of data logs to identify the threat as quickly as possible to not fail in the fight against hackers.

Technology that gives you visibility of changes inside your environment

 The business growth widens the attack surface. The increase of applications, databases, users, devices and third parties creates “dark places” in your environment. During the pandemic and work-from-home, the amount of such black zones is growing, especially if company management accepts using employees’ own devices. 

And such uncontrolled “black zones” are the best targets for attackers. They can use them as a direct entrance to your environment. Coming inside, hackers can stay invisible and just observe for further attacks, move deeper through the network, or commit a supply-chain attack. 

SIEM technology helps to mitigate the risks by identifying attacks that have been able to exploit known and unknown vulnerabilities. Besides, it uncovers and draws information from previously hidden spaces on the network, preventing hackers from concealing their malicious activities from view.

Old methods are not strong enough

According to the Ponemon Institute on the state of endpoint security risk research, only 27% of respondents thought that traditional antivirus solutions were sufficient for new and unknown threats. The reality is, with increased reliance on being connected to the web, combined with the rapid expansion of malware, it’s becoming harder and harder to prevent our devices from getting infected. That means, if relying on antivirus software alone to secure business and valuable information, an organization doesn’t have enough protection against the growing number of threats. But still, although SIEM tools have many benefits, they should not replace enterprise security controls for attack detection, such as intrusion prevention systems, firewalls, and antivirus technologies. A SIEM tool on its own doesn’t monitor raw security events as they happen throughout the enterprise in real time. SIEM uses log data recorded by other software.

SIEM technology helps businesses fight against the newly invented threats, capturing and then analyzing data from across the network, such as system and event logs, and looks for behavior patterns that could point out suspicious activity.

SIEM normalize collected data

Each component of your IT environment may generate terabytes of plaintext data per month. Think for a minute: all applications, login ports, databases, and devices. Collected data from throughout the IT environment can present a lot of challenges. Collecting all of this is not easy in itself. But each of them also generates, formats, and sends data in different ways, thus creating even more problems. Making conclusions of all of that and recognizing correlated security events indicative of a breach manually would take a lot of time. And here comes SIEM solutions with data normalization. SIEM technology reformats the data in a format comfortable for your team, allowing consistency in your log management and also easy correlation. It enables to make qualitative threat analysis processes and simplifies the work for the security team. 

Nowadays, more and more businesses are moving to the cloud. And it turns out to be such a branching: some companies are afraid to trust critical information to the cloud giant, while others, on the contrary, believe that by trusting someone “bigger,” they thus protect themselves. 

Cloud providers’ clients may think that their environment would be monitoring and they will alert on any compromises. But it doesn’t always work like this. Before moving to the cloud, it’s worth ensuring that security policies remain in place as well as reviewing what third-party providers are doing to protect assets.

Modern SIEM technologies can monitor cloud environments to ensure that data and apps in the cloud are secure.

The faster your business can respond to an attack, the less damage the attack can potentially cause

A quick threat localization and response are critical to mitigating the impact of an incident. The security team needs to identify all affected assets, resources, and connections to ensure that the incident does not come back or move further through the organization after removing containment measures. The faster the business can block suspicious IP connections, contain and remove malware, the less damage the attack will cause.

SIEM technology significantly increases the efficiency of incident handling, saving time and resources for the business. 

 A SIEM tool can improve efficiency, first of all, by providing a general interface to view all the security log data from many hosts.  

SIEM technology

  • enables a security team to identify an attack’s route through the enterprise;
  • allows identification of all the infected hosts;
  • provides automated mechanisms to stop attacks that are still in progress and to isolate compromised hosts.

The last but not least, SIEM solutions provide compliance reporting 

Businesses’ investments in complying with standards and regulations are increasing. The aftermaths of any enterprise failing to meet compliance mandates are losing sales and the legal costs of resolving lawsuits.

SIEM reporting capabilities are compliant with the requirements mandated by standards such as the Health Insurance Portability and Accountability Act (HIPAA), the Payment Card Industry Data Security Standard (PCI DSS), and the Sarbanes-Oxley Act. With SIEM logs, a company can save time and resources when meeting the security compliance reporting requirements.
