Resilient Rebound: Come riprendersi da un attacco informatico

Gli attacchi informatici possono rappresentare una realtà ineludibile per le imprese, ma grazie a un approccio strategico al cyber Recovery, le aziende possono uscirne più forti e sicure che mai.

Facing an estimated 2,244 cyberattacks daily – or un attacco ogni 39 secondi – 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.

Per i responsabili della tecnologia e della sicurezza, ciò significa elaborare una solida strategia di cyber-Recovery che non solo rafforzi il proprio ambiente contro gli attacchi, ma faciliti anche un recupero rapido e sicuro e il ritorno alle normali operazioni aziendali. Le minacce informatiche continuano a essere in cima alla lista delle preoccupazioni aziendali tra i dirigenti di alto livello, con il 75% dei dirigenti che afferma che rappresentano un rischio moderato o grave.

According to Commvault and GigaOm’s Recupero cyber Readiness Reportdi Commvault e GigaOm, l’83% dei 1.000 leader globali intervistati ha dichiarato di aver subito una violazione della sicurezza di rilievo, il 55% ha riferito di non essere pienamente sicuro di poter ripristinare sistemi e dati a seguito di un incidente grave e il 42% ha ammesso di non avere chiarezza su chi sia responsabile della resilienza informatica e del ripristino.

These data points and countless others underscore the urgent need for an exceptional cyber recovery strategy. Per mitigare i rischi e garantire la sicurezza delle operazioni, le grandi aziende devono adottare un approccio di Recovery in “camera bianca”, in cui possano isolare le minacce, esaminare attentamente l’ambiente alla ricerca di infezioni e garantire un rapido ritorno a uno stato di sicurezza.

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 creare ambienti resilienti 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.

Il ripristino informatico 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.

Le organizzazioni aziendali devono testare continuamente il proprio approccio al recupero informatico per consentire un ritorno rapido e senza intoppi alle operazioni aziendali. Un approccio strategico che preveda il ripristino in un ambiente protetto aiuterà le aziende a progredire nel loro percorso verso la resilienza informatica.
