Resilient Rebound: Como se recuperar de um ataque cibernético

Os ataques cibernéticos podem ser uma realidade inevitável para as empresas, mas, com uma abordagem estratégica de Recovery cibernética, os negócios podem sair mais fortes e mais seguros do que nunca.

Facing an estimated 2,244 cyberattacks daily – or um ataque a cada 39 segundos – technology and security leaders struggle to safeguard their environments, assets, data, and customers against determined, malicious bad actors and a relentlessly evolving threat landscape. But in the world of cybersecurity, it’s not always about how hard you get hit. It’s about how hard you get hit and keep moving forward.

Para os líderes de tecnologia e segurança, isso significa elaborar uma estratégia robusta de Recovery cibernética que não apenas fortaleça seu ambiente contra ataques, mas também facilite uma recuperação rápida e segura e o retorno às operações normais de negócios. As ameaças cibernéticas continuam no topo da lista de preocupações empresariais entre a alta administração, com 75% dos executivos afirmando que elas representam um risco moderado ou grave.

According to Commvault and GigaOm’s Recuperação Cibernética Readiness Reportda Commvault e da GigaOm, 83% dos 1.000 líderes globais afirmaram ter sofrido uma violação de segurança significativa, 55% relataram não estar totalmente confiantes de que poderiam recuperar sistemas e dados após um incidente grave e 42% admitiram não ter clareza sobre quem é responsável pela resiliência cibernética e pela recuperação.

These data points and countless others underscore the urgent need for an exceptional cyber recovery strategy. Para mitigar riscos e manter operações seguras, as grandes empresas devem adotar uma abordagem de Recovery em ambiente controlado, onde possam isolar ameaças, examinar minuciosamente o ambiente em busca de infecções e garantir um retorno rápido a um estado seguro.

Cleanroom data recovery goes beyond traditional disaster or data recovery approaches by designating a separate, controlled space to identify the root cause of security issues. The cleanroom isolates the problem in a segregated area, prevents any infected systems from spreading, and reduces the risk of data being compromised.

To start, a cleanroom is a secure, isolated environment that protects sensitive data from external threats. It is used to analyze digital evidence related to cyber incidents, breaches, crimes, or attacks. It enables security organizations to expedite investigations into incidents and speed the mean time to recovery for an organization.

In some cases, cleanroom data recovery is delivered by a cloud-based platform that allows for testing recovery points before fully restoring data to production systems. The isolated environment serves multiple purposes by keeping infected systems separate, providing space to scrutinize the environment, and preventing infection to broader systems.

Recovering to a cleanroom involves several capabilities combined to mitigate risk to the environment.

Immutable backups: Storing an air-gapped, immutable copy of data to ensure it remains untouched by attackers and provides a reliable recovery point. An immutable backup is a file that cannot be altered in any way, designed to prevent bad actors or administrators from changing the data. Immutable backups also are intended to eliminate the possibility of data being deleted. Immutable backups protect against natural disasters and human error, but more importantly an immutable backup promises that even if an environment is compromised, the data will remain secure.

Isolated testing environment: Utilizing a cleanroom where you can test and validate the integrity of backups before restoring them to production, minimizing the risk of reinfection. The segregated area provides a safe and isolated environment for testing cyber recovery plans, conducting forensic analysis, and providing continuous business if a breach does occur.

Automated recovery processes: Leveraging automated tools to quickly identify compromised systems and restore data from clean backups, which minimizes downtime. Following an attack, organizations want to resume business operations, but the process is slowed by the many applications that must be rebuilt in a step-by-step, time-consuming approach. Automation can more quickly restore an organization’s entire cloud application and data environment, including all the necessary cloud infrastructure configurations, in a much timelier manner.

Data classification: Implementing robust data classification policies categorizes data based on its sensitivity level, for instance financial data, personally identifiable information (PII), or intellectual property. This lets security leaders focus on recovering critical data first, providing minimal disruption to business operation. By using discovery tools to scan an environment, security teams can identify sensitive data across different systems and analyze file content, metadata, and access patterns to accurately classify the data. This information will help speed recovery time and keep critical systems available for business operations.

Early threat detection: Identifying and containing potential cyberattacks before they encrypt or exfiltrate critical data enables faster and cleaner recovery from ransomware or other malicious attacks by isolating clean data copies and minimizing damage to production systems. Providing an early warning system proactively protects data and minimizes the impact of a breach by isolating data copies affected by an attack. By identifying malicious activity before significant damage occurs, enterprises can respond immediately and begin mitigation strategies.

Security awareness training: Conduct regular security awareness training sessions to educate employees on the importance of cyber hygiene and security measures.

Cyber recovery provides organizations with powerful toolsfor comprehensive testing, forensic analysis, and production failover. By adopting cleanroom data recovery, organizations can confidently test their cyber recovery plans, identify and remediate vulnerabilities, and maintain business continuity in the face of cyberattacks.

Enterprise organizations must do more than recovery; they must construir ambientes resilientes that can not only withstand an attack, but also can recover without data loss, system damage, or financial pain. Effective cyber recovery can help organizations avoid financial losses, reputational damage, and legal action that can result from a malicious cyberattack.

A recuperação cibernética should be considered an ongoing process that can be continuously finetuned and honed as the organization grows more and more resilient. A cyber-resilient organization can adapt to known and unknown challenges, responding to threats and recovering from attacks in an expedited manner. By conducting thorough risk assessments, implementing strong security measures, creating an incident response plan, and regularly training employees on cybersecurity best practices, enterprises can quickly adapt to evolving cyber threats and proactively adjust their security strategies.

As organizações empresariais devem testar continuamente sua abordagem de recuperação cibernética para permitir um retorno rápido e sem atritos às operações comerciais. Uma abordagem estratégica de Recovery em um ambiente isolado ajudará as empresas a avançar em sua jornada para se tornarem negócios ciber-resilientes.
