Data security is one of the most crucial aspects of working today. Over 89% of all businesses have internet and hardware security in place. These statistics only highlight the relevance of SIEM. However, only some people are comfortable with technology and its related solutions. Worry not because businesses like managed SIEM services offer the whole package at reasonable rates. Read on to know more about SIEM and why it is indispensable.
What is SIEM?
SIEM is an acronym for Security Information and Event Management. SIEM systems collect data from various security devices, analyse it, and generate alerts. Businesses and government agencies use SIEMs to monitor their IT environments for signs of malicious activity, such as:
- Suspicious logins or connections
- Intrusion attempts (e.g., failed login attempts)
To function properly, a SIEM system must have access to information about all of your network’s endpoints—i.e., the computers and peripherals that communicate with each other over a network infrastructure. This includes access points, laptops, desktops/workstations, mobile devices (such as smartphones or tablets), printers, storage arrays…etcetera ad infinitum!
What are the benefits of using SIEM?
- Managed SIEM services help you identify security threats. Attacks on your network can be difficult to detect and manage. Still, SIEMs enables you to monitor all of the data flowing through your network and detect any suspicious activity that could indicate a security threat.
- SIEM helps you identify weaknesses in your network. Suppose an attacker gains access to one of your servers or workstations. In that case, they may be able to discover vulnerabilities that can help them gain complete control over other devices in your system.
- SIEM helps you identify potential breaches in your system’s security protocol by monitoring the traffic coming into and going out of every device on the network so that if something looks wrong (like unusual volumes or types of traffic), then it’s easy for IT staff members to investigate further before anything serious happens; this also gives them time
How does SIEM work?
When you install a SIEM, your system collects data from multiple sources. These could include logs, security devices such as firewalls and IPS/IDS systems, network activity and other sources. The system then analyses this data to identify any malicious or suspicious behaviour.
Once it’s collected the relevant info, it can alert you when something happens that seems suspicious or out of place: for example, if someone tries to log in from an unusual location or if they’re trying to hack into your website.
Data Collection and Analysis
Managed SIEM Services to collect and process data from a variety of sources.
- File integrity monitoring (FIM) tools monitor changes to files that could indicate attempts to exploit vulnerabilities in a computer system.
- Network security information and event management (NSEM) solutions collect and store network traffic data, including information about users, computers, applications, devices, protocols and other events that occur on the network.
- Endpoint detection systems (EDS) monitor operating system processes on endpoints such as laptops or desktops for signs of suspicious activity, such as malware infections or unauthorised access attempts by hackers. They can also monitor file integrity by tracking changes made by application programs running on the endpoint device’s operating system to files stored on the device’s hard drive or removable storage media such as USB flash drives and SD cards; if an authorised user does not authorise these changes then it is possible for an attacker using stolen credentials to have made them maliciously – this type of attack is known as “file injection.”
What features should you look for in a SIEM system?
You should look for a SIEM system that can collect data from various sources, such as your organisation’s security cameras, firewalls and other network devices. It should also be able to correlate that information with data from other sources, such as NAC (network access control) systems and email servers.
A good SIEM solution will include an alerting system that can monitor log files or network activity to trigger alerts when certain conditions are met. For instance, if an attacker attempts to log into your company’s bank account through the web portal but fails because they don’t have the right permissions, then you’ll want the SIEM solution monitoring it to generate an alert indicating that something suspicious has occurred on your website during this time frame.
In addition to providing alerts about possible threats in real-time, you’ll want your new SIEM system to provide reports on historical data so you can analyse trends over time. Setting up these reports effectively requires careful planning: You’ll need someone who understands how different types of threats manifest themselves in different ways across various systems.
