Small and midsize businesses are not immune to becoming the target of a crippling cyberattack and without the proper procedures in place business owners risk the very real threat of a large-scale assault on their company’s data. Would you be able to recover if your organization was attacked?
Instances of cybercrime have reached an all-time high and ensuring that your company has the procedures in place to guard against an army of determined fraudsters is more important than ever. But before you can implement effective controls, you must have a clear understanding of what it is that threatens your business.
Know Your Enemy
Ransomware has become a formidable threat to businesses of all sizes, yet I have worked with quite a few business owners who are unfamiliar with the term. This is particularly unnerving as a Ransomware attack can be catastrophic to the financial stability of your business.
Ransomware is the infection of a computer which immediately encrypts all recognizable file types. Once your network is infected, a screen appears on your monitor demanding that the company pay a ransom in exchange for the data to be “decrypted” and released. A time frame is established by the hackers and it is made clear that if the ransom is not paid before the deadline, the organization’s data will be destroyed.
4 Tips To Help Prevent A Ransomware Attack
To protect your business against Ransomware and other similar threats:
- Train your employees to identify phishing emails.
Numerous vendors can provide your company phishing tests and video training to help educate your employees about phishing emails and ways to identify possible scams. Specifically, work to change the mindset of those within your organization when it comes to opening attachments and clicking on hyperlinks.
- Set employee Microsoft Active Directory rights.
It’s unlikely that all your employees will need full-access to your company’s entire database to do their jobs. One way to protect your data is to only grant access to the data needed for employees to complete their job responsibilities. This way, if an attack does occur, the damage can be isolated.
- Consider implementing programs such as Microsoft “AppLocker.”
When you implement programs like AppLocker, you require users to be assigned access to the programs they need to utilize. Again, this helps to isolate the threat which can help minimize the impact of an attack.
- Implement a Disaster Recovery (DR) Plan.
Some research indicates that only about 35 percent of small- to medium-sized businesses have a working and comprehensive disaster recovery plan. We are learning time and time again just how important it is to have a plan in place to protect your business when crisis strikes. A DR plan, complete with regular plan testing and offsite backup data, will help prepare you for unforeseen events which, under current circumstances, could prove to be catastrophic.

Guard Your Data With These Best Practices
Monitor for irregularities
If your network is infected, you can eliminate or decrease the threat of Personally Identifiable Information (such as financial records, medical information or intellectual property) from being infiltrated by utilizing an Intrusion Detection System or Security Information & Event Management application or service. These applications are designed to monitor for invalid access attempts, outgoing traffic identification and other significant alerts.
Require two-factor authentication
Many breaches are the result of access that has been granted to a third-party vendor. Oftentimes the vendor’s network will become infected and can lead to the breach of your own organization. While the data breach may not have originated within your organization, you are responsible for the inroads that were ultimately exploited by hackers to gain access into your network. A best practice is to require all vendors to utilize two-factor authentication or direct contact with your IT staff in order to gain access to your company’s network. Your networks should never be directly accessible to any outside vendor.
These tips can help you protect your organization from cybercriminals, but they only provide an initial layer of security. New threats are being developed every day and existing threats are evolving rapidly. The best thing you can do is arm yourself with knowledge and regularly test for weaknesses in your company’s armor. One day, your business will be the focus of a cyberattack. Will you be ready?
An IT Audit can help determine if you have the right systems in place to protect your business from these threats. Email Rea & Associates for more information about how you can protect your company’s data from those who mean to do harm to the business you have worked so hard to build.
