For many of us, one of the worst professional scenarios we can fall victim to is the dreaded data breach. However, as companies expand their digital footprint, so does their risk of experiencing this nightmare. Breaches have far-reaching consequences, including hefty financial losses and a massive hit to your reputation. For organizations that have become statistics, it’s imperative to act quickly and take steps to recover from the effects of a data breach and prevent another. This article explores what it takes to pull off a data breach recovery and the subsequent steps to avoid future attacks.
According to Verizon’s 2023 Data Breach Investigations Report, 83% of breaches are caused by external actors. The most common attack methods include social engineering, software misconfigurations, and human error. Size doesn’t seem to be a deterrent, with companies like T-Mobile and Meta falling victim to data breaches over the past two years.
Many companies use online systems, such as cloud computing, to remain competitive. Many have adopted work-from-home (WFA) and hybrid work models to give employees more flexibility. While those policies empower workers and businesses, they also put customers, workers, and vendors at a higher risk of cyberattacks.
A swift reaction to a data breach affects a company’s overall liability, ability to continue operating, and overall reputation. While it’s never fun for a company to see its brand spotlighted for the wrong reasons, data breaches are a wake-up call that emphasizes the importance of a strong security posture. It’s a time to focus on the importance of a robust security posture, data privacy and security, and making cybersecurity threats a company-wide concern.
Breaches are becoming more common due to increasingly sophisticated attacks by malicious hackers. Organizations are also at risk when employees fall for social engineering attacks, in which bad actors fraudulently attempt to obtain their credentials. Combining the two leaves the average company only a few steps away from experiencing a critical incident.
Frequent causes of data breaches include:
The biggest worry after a data breach is the risk of hackers leaking stolen records. While it’s one thing for the business to be harmed, if a customer’s personally identifiable information (PII) is compromised or exposed, it will inevitably lead to further damage, like identity theft or financial fraud. Those kinds of escalations compound the problem significantly. The following are the steps an organization should take immediately after a data breach.
Remove any affected data and document the attack’s impact. The IT team should conduct a data breach investigation and collect evidence of what happened. They should also identify every compromised system and server. That information can help inform cyber forensic analysis, making it easier to determine how a hacker gained unauthorized access.
Disconnect systems, devices, and networks from the affected access point. Moving quickly limits the scope of an attack from a bad actor. Confer and consult with individuals who understand the effects of turning off potentially compromised systems.
Once a data breach has been identified, remove or restrict access to the affected information. This information should be reviewed only by those involved in the recovery effort or with a pressing business need. That way, cybercriminals can’t hijack employee credentials and get back in. Limiting access also allows response teams to update security measures like firewalls and anti-malware software.
Depending on how a hacker gained access and the extent of the data breach, consider resetting passwords across the organization. If a hacker compromised other accounts, that can prevent them from taking advantage of that access. It’s also a good idea to establish a policy requiring employees to reset their passwords at set intervals. Employing protocols such as multi-factor authentication (MFA) also enhances password security.
A data breach response plan is critical to mitigating the damage from a data breach. It’s also an excellent way to get peace of mind and prepare for future attempts.
Pull together representatives from areas like IT, legal, communications, and management. Everyone on the same page is essential to formulating a rapid response to a data breach. Once everyone is together, establish a clear chain of command and assign responsibilities to each team member.
Next, develop a communication strategy to inform all affected parties. The team should provide status updates to all required legal entities by the timeline set in regulatory guidelines. A company’s communication strategy should also include informing relevant stakeholders.
Inform customers and employees about the issue and what is being done to fix it. Both groups should hear from the company rather than learn about the incident from a headline.
Establish a timeline for data breach recovery. This helps streamline the process and prioritize remediation efforts based on their risk level. The plan should cover identifying the cause of a breach, containing the damage, and restoring data and affected systems.
Employing real-time threat detection and response tools is an excellent way to identify and remediate the root cause of a data breach. They help diagnose the issue and reinforce security. Businesses should also review their overall attack surface. That includes going over the security environments of third-party vendors.
Network security penetration testing, or pen testing, helps reveal vulnerabilities in a business’s server infrastructure. They simulate real attacks on a company’s data, allowing cybersecurity teams to identify weaknesses in applications and servers while assessing the strength of an organization’s security posture.
Does dealing with and recovering from a data breach sound like a horrific ordeal? That’s because it is. Not only is it a complete disruption, but it’s a total violation and a perfect example of where an ounce of prevention is worth a pound of cure.
Kiuwan’s end-to-end application security platform helps businesses identify vulnerabilities that could lead to data breaches. The platform aligns with security standards like OWASP, CWE, and NIST. It supports over 30 major programming languages and frameworks. Click the link below to get your free demo!
