A data breach can significantly damage a business. It can result in the loss of proprietary information, damage to the company’s reputation, and costly remediation. The average data breach costs a business millions of dollars, but the impact extends beyond finances. How can a business prevent these attacks?
Data and Sensitive Information
To protect its data, a company must know where this data is located and what it contains. All data sets must be inventoried, and all locations must be determined. In addition, the company needs to regularly update its inventory and locations to ensure it is always aware of where data is. Furthermore, businesses that need a cloud fax provider or another third-party service must ensure the service selected conducts this inventory and knows the location of its sensitive client information.
Limit Access
Business owners must limit access to sensitive data. Only those employees and contractors who must view this information should be granted access. Sadly, many business owners offer privileged access to those who don’t truly need it and put their data at unnecessary risk when doing so. By establishing and enforcing policies regarding privileged access, the business owner can reduce the risk of a data breach. They must ensure regular oversight of this data and use access management tools to facilitate and enforce the policies.
Infrastructure Patches
IT security teams must monitor their networks and systems. When a security patch is offered, it needs to be used immediately. Zero-day exploits remain a problem today, so IT security teams must be aware of this and immediately take action when a manufacturer issues a software patch. Doing so will reduce the risk of unauthorized access to sensitive data.
Network Perimeter
Network perimeter security serves as the first line of defense against unauthorized access. Many companies use firewalls, and they may also benefit from intrusion prevention and detection systems. Access control lists are popular among business owners, and they often turn to other tools to ensure business data can flow internally while identifying and stopping outside threats.
Endpoint Security Controls
Every business needs endpoint security controls in place. For example, malware detection software is essential today. As the distribution of users and workloads expands, traditional perimeter security tools become less useful. Endpoint security, when properly implemented and managed, offers the highest level of security against internet-based threats.
Lateral Movement
When a cybercriminal successfully overcomes the company’s perimeter security, they immediately look for other systems they can access and infiltrate. Limiting unsanctioned lateral movement can stop them in their tracks. Microsegmentation is helpful because it establishes isolated network zones.
Data Encryption
Companies often focus on encrypting data during transmission. Sensitive data should also be encrypted at rest to prevent unauthorized parties from accessing it. Never assume a corporate network is secure. Always encrypt the data even as it moves internally.
Password Policies
Countless data breaches occurred because employees did not have robust passwords. Business owners must require passwords for all applications and services running on their network. These requirements might include a minimum password length, multi-factor authentication, or mandatory monthly or quarterly password changes.
Training
Any person with access to sensitive data must undergo comprehensive cybersecurity training. Employees and contractors are two groups that need this training. Whether intentional or unintentional, mistakes on the part of staff, contractors, and partners continue to be a significant threat to data security. This area is also the hardest to protect against. Regular training can reduce the risk.
Data breach prevention is essential. However, companies must also focus on other areas. Business owners must find the right mix of cybersecurity policies for their organizational risk appetite. When the right mix is found, business productivity increases while the risk of a security incident goes down. Every business wants this.
