Cloud computing’s benefits are ubiquitous in right now’s digitally dominated panorama. Greater than 80% of organizations leverage Microsoft Azure or Amazon Internet Providers (AWS) right now.
Nonetheless, securing these dynamic environments stays a problem for a lot of. Cloud servers particularly are some of the frequent vectors focused by menace actors as a result of they’re usually used to retailer organizations’ delicate credentials, information, and business-critical functions. Defending cloud servers carries a few of the similar challenges and threats as conventional on-premises servers, however there are additionally cloud-specific nuances that safety groups should handle by including an extra safety layer on high of the normal endpoint safety.
A multi-layered safety strategy that integrates agent-based and agentless applied sciences allows real-time menace detection, assault disruption, and proactive posture administration, permitting safety groups to proactively and reactively reply to threats.
Defending digital machines (VMs): A posh problem
Each VMs and the cloud environments through which they function are extremely dynamic. And whereas this dynamic nature is nice for enterprise scalability, it may possibly additionally enhance the scale of your assault floor. Due to their capacity to be provisioned on demand, VMs usually have shorter lifespans in comparison with conventional on-premises servers. This makes it tougher to deploy and handle conventional safety brokers which are designed for long-term installations.
Moreover, conventional safety options usually deal with defending the working system (OS) of a VM. Nonetheless, in fashionable cloud functions, servers are susceptible to threats ensuing from conventional vulnerabilities and misconfigurations inside the VM working system and outdoors of it, within the cloud administration airplane. This requires a extra holistic strategy to safety that addresses the complete stack, together with the administration airplane, networking configurations, and extra. Moreover, as a result of cloud servers usually are not siloed environments, real-life assaults can hop between the server working system and the remainder of the cloud or vice-versa. This additional underscores the necessity for a holistic cloud server strategy. Analysis from Microsoft’s 2024 State of Multicloud Safety Danger Report discovered that the common multicloud property has 351 exploitable assault paths that result in high-value belongings. Over 70% of malicious entities are energetic for lower than two hours, so defenders have a restricted period of time to detect and reply to those threats.
Risk actors are actively capitalizing on these challenges. For instance, Octo Tempest is infamous for deploying strategies—together with cloud-native assault ways, strategies, and procedures (TTPs)—to navigate out and in of cloud environments, together with exploitation of cloud administration instruments to compromise servers. Upon attaining entry to the cloud by way of compromised credentials or social engineering schemes, the group will usually transfer laterally into susceptible VMs the place they’ll compromise and ransom beneficial enterprise assets.
Defend servers in any surroundings with built-in agent and agentless capabilities
To safeguard servers within the cloud, organizations should undertake a hybrid strategy that mixes confirmed safety practices like endpoint safety brokers with cutting-edge cloud-native agentless options. This strategy delivers one of the best of each worlds and empowers groups to guard all environments, whether or not on-premises, hybrid, or multicloud.
Server safety with a single agent for endpoint safety offers automated VM discovery in addition to real-time detection and disruption of assaults. The agent’s efficiency is optimized for servers. In contrast, cloud-native agentless capabilities present large, frictionless protection on multicloud servers. This agentless strategy provides instantaneous visibility into posture points, cloud-native detections, and potential assaults with out requiring a dependency on workload homeowners. When utilized in tandem, the agent offers elementary endpoint safety and real-time capabilities whereas the cloud-native agentless strategy enhances the cloud’s distinctive wants to offer wider visibility the place brokers are troublesome to deploy.
As organizations proceed emigrate operations to the cloud and develop their digital footprint throughout complicated hybrid and multicloud environments, they want a complete answer that may seamlessly defend in opposition to on-premises and cloud-specific safety threats. By integrating a unified agent and agentless strategy, safety groups can ship in-depth safety with frictionless, broad protection throughout multicloud servers.
