Let’s face it—nobody enjoys contemplating worst-case scenarios. However, in today’s digital landscape, cyberattacks are more a matter of “when” than “if.” The stakes become even greater when operating your business on AWS.
Cloud platforms offer adaptability and expandability, but they also present fresh security obstacles that may seem daunting. So, how can you ensure that when (inevitably) something goes amiss, your systems remain intact?
In this manual, we’ll provide a simple, practical examination of enhancing the cyber resilience of your AWS setup.
It’s not just about bolstering your defenses with trendy jargon—this is about constructing a multi-faceted, actionable scheme that guarantees your business remains operational even amidst an attack.
What does cyber resilience entail?
Let’s begin with the fundamentals: cyber resilience goes beyond cybersecurity. The National Institute of Standards and Technology (NIST) delineates cyber resilience as “the ability to anticipate, withstand, recover from, and adapt to adverse conditions, stresses, attacks, or compromises on systems that include cyber resources.”
It’s not just about thwarting attacks; it’s about readiness for their occurrence, minimizing the impact, and swift recovery.
NIST furnishes extensive guidance on cyber resilience in their SP 800-160 Vol. 2, Rev. 1 report, outlining a framework to aid businesses in crafting a robust resilience strategy.
At the heart of this framework lie four pivotal objectives:
- Foresee threats before they materialize
- Endure assaults when they transpire
- Recuperate from any interruptions
- Adjust your systems to fortify preparedness for future threats
Each objective bolsters decision-making across business operations and systems, aiding organizations in comprehending their risk and resilience status.
The cruciality of cyber resilience for all entities
Recent data from JupiterOne underscores a 589% surge in the cloud attack surface, indicating a rapid proliferation of potential attack vectors.
With the skyrocketing adoption of cloud services, ventures now contend with a heightened number of cyber assets—and consequently, an increased array of vulnerabilities.
In addition to this, the exigencies stemming from remote work and the imperative for a robust cyber resilience strategy have become more acute than ever.
A robust cyber resilience strategy engenders several notable advantages:
- Alleviating financial losses: Swift recovery from attacks mitigates the financial ramifications for your enterprise.
- Enhancing client trust: Clients gain a sense of security knowing their data is safeguarded.
- Minimizing downtimes: Accelerated recovery durations ensure smooth operation continuation.
- Meeting regulatory mandates: Resilience measures aid in compliance with data safeguarding statutes.
In essence, cyber resilience isn’t only about upholding your business’s security—it’s about preserving operational continuity in the face of any peril.
Reasons for cloud security lapses
Despite the scalability and adaptability cloud technology offers, it introduces fresh security dilemmas. Conventional cybersecurity tools frequently struggle to provide comprehensive protection within cloud settings, leading to exploitable gaps for cyber adversaries.
A study by Sysdig revealed that approximately 75% of companies utilize cloud services harboring high or critical vulnerabilities.
Perils in cloud security
- Burdening a single person with security roles. Too frequently, organizations bestow both SecOps (Security Operations) and DevOps (Development Operations) responsibilities upon a solitary individual or a small team.
- While this may seem like an efficient resource utilization approach, it can swiftly lead to exhaustion and oversights. DevOps and SecOps are intricate, distinct roles, each demanding specialized expertise. When one person is thinly spread across both roles, vulnerabilities can easily slip by.
- Duties such as patch management, continuous monitoring, and secure coding practices may be disregarded, creating security loopholes for assailants to capitalize on. Assigning these responsibilities across a broader team ensures heightened focus and fewer overlooked vulnerabilities.
- Security ≠ Detection. Understanding that detection is merely the initial phase is crucial. Many entities fall into the fallacy of assuming they are safe once a detection mechanism is in place.
- Detection in isolation falls short; a detected breach can still inflict substantial harm if there isn’t a response plan in place. Protocols for post-detection actions—such as isolating affected systems, notifying key stakeholders, or initiating disaster recovery—are imperative.
- It’s the response that curtails damage and expedites recovery, not merely awareness that something is amiss.
- Lack of simulation and testing. Implementing security controls sans testing is akin to setting up a fire alarm but never verifying its functionality. Numerous organizations neglect attack simulations in cloud environments, rendering them unprepared for actual incidents.
- Regular penetration testing and red team exercises are necessary to simulate cyber incursions and identify deficiencies in your defense scheme.
- Testing disaster recovery blueprints ought to occur frequently, not annually, to guarantee successful backups restoration and rapid system reactivation. Delay stress-testing your security systems, and you’ll realize they are ineffectual—when it’s too late.
- Continuous 24/7 monitoring. A prevalent error various businesses commit is underestimating the need for ceaseless monitoring. Cyber threats are incessant, necessitating perpetual defenses.
- While automated systems are solely as effective as the configured parameters, without human oversight, critical issues may slip under the radar.
- Constant 24/7 monitoring ensures vigilant monitoring for anomalous behavior, coupled with real-time responses upon incident occurrence. It’s beyond mere attack interception but preempting substantial damage.
- Inadequate role demarcation in cloud environments. As organizations expand and cloud environments grow intricate, segregating responsibilities within teams becomes imperative.
- Permitting multiple individuals or teams access to cloud environments heightens the insider threat or inadvertent modifications risk. Clear role delineation within your cloud security protocols guarantees that only authorized personnel execute specific actions,
- Tasks such as adjusting settings or accessing confidential information.
- Conducting regular audits on access controls can pinpoint weaknesses in your security measures and deter unauthorized actions.
- Dependency on outdated tools in cloud setups. While traditional security tools might have sufficed for in-house setups, they often lack effectiveness in cloud environments.
- Cloud environments demand distinct security frameworks and resources to manage the intricacy and size of cloud operations.
- For instance, conventional firewalls or intrusion detection systems may not sufficiently cover the dynamic and dispersed cloud workloads. Organizations should embrace cloud-native security solutions, such as those from AWS, to ensure adequate protection. Cloud-native tools are specifically engineered to blend with cloud services and offer real-time visibility for enhanced security.
- Failure to consistently patch and update. One of the most basic yet commonly disregarded aspects of cloud security is regular patching. Neglecting to apply patches or security updates renders your cloud environment prone to known vulnerabilities.
- Attackers are continually searching for unpatched systems; even a minor delay in applying a critical patch could lead to a breach.
- Many organizations overlook patches due to concerns of downtime or simply overlook them, particularly in setups with numerous cloud resources.
- An automated patch management system can guarantee the application of all critical updates across your cloud environment without manual interference.
- AWS GuardDuty: Monitors for malicious activities and unauthorized conduct.
- AWS Shield safeguards against Distributed Denial of Service (DDoS) assaults.
- AWS IAM (Identity and Access Management): Facilitates control over resource access.
- AWS Inspector: Evaluates vulnerabilities within your cloud setup.
- MITRE Engage: Instructs defenders in engaging and misleading adversaries.
- D3FEND: Offers a knowledge base of cybersecurity countermeasures.
- CALDERA: Automates adversary simulation to evaluate network resilience.
- Cyber Resiliency Engineering Framework (CREF) Navigator: Aids in aligning cyber resilience goals with business objectives.
