Organizations are shifting their IT infrastructure from on-premises to the cloud to gain advantages in cost, productivity, and uptime. Though cloud offerings are typically highly secure, the possibility of a cyberattack should not be overlooked. As the number of organizations moving to the cloud increases, this brings its own set of security challenges.

The popularity of Linux servers has grown recently, grabbing the attention of hackers. As detection techniques advance, attackers are adopting new and surreptitious methods to stay undetected, and accomplish their nefarious motives.

Spotting the attack

Spotting and stopping attacks are vital to ensure data security. To detect cyberattacks efficiently, it is important to stay vigilant about activities happening in your network.

For instance, after an initial successful Secure Socket Shell (SSH) brute-force attack, the attacker delivers a further payload to the host by downloading scripts. Once complete, the attacker continues to move laterally, accessing sensitive data.

The attacker then lists multiple URLs to execute scripts, and finds an active IP to host. Once completed, this process enables the attackers to make changes to the directory and take down the network. Most of these exploits are carried out from the /temp folder in the directory.

A common indicator to identify these kinds of attacks is the sudden change in the amount of traffic. Monitoring network traffic helps identify potential attacks and keep hackers at bay.

Combating against attacks

There are common methods that attackers follow to gain access into the network. However, targeted attacks are tailor-made based on the sensitive security system information about the organization that the attacker has.

One of the best ways to combat an attack is to employ a solution to monitor your cloud infrastructure, script execution, abnormal CPU usage, suspicious logons, etc. This comprehensive tool should also detect activities, like the downloading of suspicious files, and provide real-time alerts and extensive reports that assist with regulatory compliance.

Here are some basic capabilities your solution should include:

  1. Identifies common attack vectors and indicators
  2. Monitors endpoints
  3. Detects configuration and permission changes
  4. Correlates security events

How can Log360 help?

ManageEngine Log360, a comprehensive SIEM and cloud monitoring tool, identifies and mitigate threats quickly and efficiently. With real-time alerting and out-of-the-box reporting, this solution helps secure your cloud platform from threat actors.

The solution monitors network activities and provides insightful information to IT administrators based on actions necessary to mitigate the impact of an attack.

Log360 provides reports on User Activities, Permission Changes, Databases, DNS, and more in your Azure environment.

For instance, when a user makes several unsuccessful login attempts followed by a successful login, Log360 alerts the IT admin. The IT admin can then generate a Recent Failed Logins report that helps identify malicious users.

The solution provides several reports on network traffic, such as Denied Flow Reports, Allowed Flow Reports, All NSG Traffic Events, etc. It also monitors IP permission changes which may be a sign of IP spoofing where the attacker tries to impersonate a legitimate IP address using spoofed Address Resolution Protocol (ARP) messages.

Log360 is also capable of monitoring virtual machine (VMs) created in Azure. The solution provides extensive reports on events such as creation, deletion, modification, etc. of VMs.
