2017 was chock-full of security threats, attacks, and breaches. Therefore, 2017 was also chock-full of lessons to be learned regarding business cybersecurity. For this week’s tip, we’ll review a few lessons that hopefully weren’t missed.
Lesson One: Keep Track of Your Data
When Yahoo and Equifax announced that huge amounts of their client data had been breached, it became clear that even some of the biggest organizations that are most reliant on security are severely lacking in their security, especially where their data is concerned.
As this was observed, it also became clear that small or medium-sized businesses need to be more careful with their data security. After all, if such large organizations were able to be breached--and for these breaches to have gone unnoticed and then unannounced for months--an SMB needs to make sure that its data is accounted for and secured against threats.
Lesson Two: Patches are Pretty Important
As we said above, 2017 saw plenty of breaches, a sizable amount of which could have been prevented by deploying patches in a timely manner, especially in the Equifax case. Patches are, appropriately enough, what developers create to resolve security issues, or ‘holes.’ However, as 2017 proved, everyone needs to do a little better where patches are concerned.
First of all, developers need to improve their turnaround when it comes to releasing patches. For instance, the patch for the bug that enabled the EternalBlue exploit wasn’t released until a month after EternalBlue was disclosed. Meanwhile, the exploit was used to enable attacks like WannaCry and NotPetya.
This brings us to businesses like yours. Without applying patches in a timely manner, any organization is leaving themselves vulnerable to attacks that leverage what a patch could have resolved.
While you can’t control when a patch for an issue will be released, you can control when that patch is applied to your systems. The longer the patch goes unapplied, the longer you allow yourself to be vulnerable.
Plus, let’s say Microsoft releases a patch for a security vulnerability that hasn’t been discovered by the public. Once the patch is out, hackers can take it apart and find out what the vulnerability is and use it to attack those who are slow to apply the fix.
Lesson Three: There are Plenty of Ways for Data to Be Stolen
If you were asked, between ransomware and social engineering (like business email and account compromise, or BEC, attacks), which was the more profitable approach for cybercriminals, which would you guess? If you were leaning toward BEC attacks, you’d be right--Cisco found that BEC attacks are five times more profitable than ransomware attacks. According to the Federal Bureau of Investigation, business email and account compromise attacks have lost businesses over $5 billion.
Businesses also need to make sure that all of their endpoints feature the same security measures, as it is much easier for a threat to gain access to your business network from a relatively unprotected endpoint that it would be for that threat to gain access to the highly-protected, real prize directly. Access controls can help prevent a threat from accessing everything from a single endpoint, and security training can help your business endpoints recognize threats and mitigate them.
There is no denying that 2017 saw plenty of stress via security issues. Learning from this stress and adjusting based on it can help 2018 be more secure. For more assistance with your security, reach out to Nexela at (215) 525-3223.
