How to avoid falling victim to ransomware

We hear routinely in the news that a major corporation or government agency has had its data integrity compromised, with millions of pieces of personal data accessed. In these cases the criminals behind the attack hope to get money by selling that data to other criminals. In the case of ransomware, the criminals want your money, and try to get it by holding your data hostage. Plain, old fashioned kidnapping with a hi-tech spin.

What can you do to avoid falling victim?

Prevention is the best cure. Follow standard “data hygiene” principles that you probably hear about all of the time. Update your OS, software, and apps whenever a new release or patch is released. Do this ASAP. Some patches may be released solely as a result of the discovery of a vulnerability. Watch out for phishing scams. If anything looks “off” about an email, don’t open it. And never open links you aren’t totally sure of. If unsure, send an email back to the sender to verify they actually sent you a link.

The most important thing you can do to make sure your data cannot be held ransom is strictly adhering to a regimen of backups. Routine backup your data. However, even backups may not be foolproof. If your data has been infected and you are unaware of it, or the backup is not segregated from your network, your backups may also be corrupted. Given the severe consequences of a ransomware attack, consider having a security evaluation done by a managed service provider who will have the security expertise to advise on the best backup protocols for your situation.

Is the Cloud really risk-free?

Is the Cloud really risk-free?

The Cloud presents plenty of benefits that make it a very attractive choice, especially for SMBs who don’t want to be burdened with higher in-house IT costs, putting your data in the Cloud is not risk-free. Just as storing data on physical servers has its security threats, the Cloud presents certain security concerns as well. These include

  • Data breach: A data breach is when your data is accessed by someone who is not authorized to do so.
  • Data loss: A data loss is a situation where your data in the Cloud is destroyed due to certain circumstances such as technological failure or neglect during any stage of data processing or storage.
  • Account hijacking: Like traditional servers, data in the Cloud could be stolen through account hijacking as well. In fact, Cloud account hijacking is predominantly deployed in cybercrimes that require entail identity thefts and wrongful impersonation
  • Service traffic hijacking: In a service traffic hijacking, your attacker first gains access to your credentials, uses it to understand the online activities that happen in your domain and then uses the information to mislead your users or domain visitors to malicious sites.
  • Insecure application program interfaces (APIs): Sometimes, Cloud APIs, when opened up to third parties, can be a huge security threat. If the API keys are not properly secured, it can serve as an entry point for cybercriminals and malicious elements.
  • Poor choice of Cloud storage providers: A security lapse from the Cloud storage provider’s end is a huge security concern for businesses. It is very important to choose a trusted and experienced Cloud service provider who knows what they are doing.

Apart from the above, there are some common threats that apply to both the Cloud and traditional data storage environments such as a DDoS attack, or a malware attack where your data in the Cloud becomes susceptible because it is being shared with others and at other places.

Some Cloud security mechanisms that SMBs can invest in to keep their data safe

Cloud firewalls: Much like the firewalls you deploy for your local IT network, Cloud firewalls work to prevent unauthorized Cloud network access.

Penetration testing: Penetration testing is a sort of a Cloud security check where IT experts try hacking into the Cloud network to figure out if there are any security lapses or vulnerabilities that could serve cybercriminals.

Obfuscation: In obfuscation, the data or program code is obscured on purpose such that the system delivers unclear code to anyone other than the original programmer, thus mitigating any malicious activity.

Tokenization: Tokenization is the process of replacing sensitive data with unique identification symbols that retain all the essential information about the data without compromising its security.1

Virtual Private Networks (VPN): Another, more commonly used mechanism is the VPN. VPN creates a safe passage for data over the Cloud through end-to-end encryption methodology.

Investing in a good Cloud security system is a must, but, in the end, you also need to remember that Cloud security is not only about antivirus software, firewalls, and other anti-malware tools. You need to pick the right MSP and work closely with them to implement a Cloud security solution that works for you.
