Best Practices to Prevent Data and Privacy Breaches

Best Practices to Prevent Data and Privacy Breaches: Before we get started, let’s define what we’re talking about. The term security breach can conjure up all sorts of meanings, but I’d like to focus on how it relates to information technology. So by definition –

Security breach: “A situation where an individual intentionally exceeds or misuses network, system, or data access in a manner that negatively affects the security of the organization’s data, systems, or operations.”

When it comes to data breaches, the risk for organizations is high, from the easily calculable costs of notification and business loss to the less tangible effects on a company’s brand and customer loyalty.

Let’s look at some ways that will significantly increase the effort required to breach the security of your network and computers.

Best Practices to Prevent Data and Privacy Breaches

1. Change Default Passwords

It’s surprising how many devices and applications are protected by default usernames and passwords. Attackers are also well aware of this phenomenon.

Change Default Passwords

Not convinced? Run a Web search for default passwords, and you will see why they need to be changed. Using a good password policy is the best way to go, but any character string other than the default offering is a huge step in the right direction.

2. Never Reuse Passwords

On more than one occasion, you must have run into situations where the same username/password combination was used over and over realizing it’s easier.

Never Reuse Passwords

But if you know this, I’m pretty sure the bad guys do as well. If they get their hands on a username/password combination, they’re going to try it elsewhere. Don’t make it that easy for them.

3. Look Beyond IT Security

To eliminate threats throughout the organization, security must reach beyond the IT department.

Look Beyond IT Security

A company must evaluate employee exit strategies (HR), remote project protocol, on- and off-site data storage practices, and more-then establish and enforce new policies and procedures and physical safeguards appropriate to the findings.

4. Establish A Comprehensive Data Loss Protection Plan

Your efforts will demonstrate to consumers and regulators that your organization has taken anticipatory steps to address data security threats.

Establish A Comprehensive Data Loss Protection Plan

Disseminate this plan throughout the management structure to ensure everyone knows what to do in the event of a breach.

5. Examine Security Logs

Good administrators know about baselining and try to review system logs on a daily basis. Since this article deals with security breaches, I’d like to place special emphasis on security logs, as they’re the first line of defense.

6. Do Regular Network Scans

Comparing regular network scans to an operational baseline inventory is invaluable. It allows the administrator to know at a glance if and when any rogue equipment has been installed on the network.

One method of scanning the network is to use the built-in Microsoft command net view. Another option is to use freeware programs like NetView. They’re typically in a GUI format and tend to be more informative.

7. Provide Training and Technical Support to Mobile Workers

Ensure that the same standards for data security are applied regardless of location, by providing mobile workers with straightforward policies and procedures, ensuring security and authentication software is installed on mobile devices and kept up-to-date, and providing adequate training and technical support for mobile workers.

8. Keep Security Software Updated (Or Patches)

An unpatched system is, by definition, operating with a weak spot just waiting to be exploited by hackers.

Admittedly, applying patches takes time and resources, so senior management must provide guidance on allocations and expectations.

9. Don’t Rely On Encryption as Your Only Method of Defense

Encrypting data in transit and at rest is a best practice, but, when used alone, it can give businesses a false sense of security.

Although the majority of state statutes require notification only if a breach compromises unencrypted personal information, professionals can and do break encryption codes.

10. Monitor Outbound Network Traffic

Malware is becoming sophisticated enough to avoid detection. One method of exposing it is monitoring outbound network traffic. Suspicions should be raised when the number of outbound connections or the amount of traffic deviates from normal baseline operation.

 

To tell the truth, it may be the only indication that sensitive information is being stolen or that an email engine is actively spamming.

These methods are simple to implement and will surely go a long way toward making it more difficult for a security breach to occur.

So these are the Best Practices to Prevent Data and Privacy Breaches.
