Ransomware has rapidly become the single largest cyber threat we face today and if the first half of 2021 was any indication, things are only going to get worse. Colonial Pipeline, Kia Motors, JBS Foods, Kaseya and CNA Financial have been some of the more notable, high-profile attacks this year. In the case of the Colonial Pipeline, the attack impacted over a dozen U.S. states and cost the company $5 million. Colonial Pipeline was able to recover ~$2.3M of the ransom, but that is often not the case. CNA Financial was not as fortunate and needed to pay an estimated $40 million to retrieve the encryption keys for their data. And ransom from the Kaseya attack, which impacted an estimated 800 to 1,500 businesses, is said to be in the range of $70M which would make it the largest ransom ever paid (should Kaseya decide to pay).Read More
Cloud security is a constant concern for organizations of every size. Stopping malicious actors from accessing your company’s systems and data is a top priority, but is made difficult by the number of different exploit techniques coupled with the sophistication of the attacks. One area of particular concern is legitimately compromised user credentials. For example, if a password I use frequently (maybe even a strong one) is exposed in a breach of an e-commerce company. The malicious actor located in Moscow who obtains this userID (likely an email of mine) and password then does a quick lookup on LinkedIn and finds that I work at Daymark. From here, the exploit is obvious. They now have a legitimate username and password combination and while we do employ multi-factor, there are constant threats to that.Read More
Properly securing assets is a constant challenge for IT. Staying one step ahead of the bad actors is a never-ending job and with a well-known shortage of IT security professionals, it’s critical that those of us responsible for protecting systems, networks and data are smart about deploying tools that will help remediate or minimize cybersecurity risks. Microsoft built Azure Security Center to help. It aligns Azure resources with Microsoft best practices to mitigate risks associated with security vulnerabilities that could lead to a breach or other security incident.

As COVID forced organizations around the world to send their workforce home, creating the work from home (WFH) phenomenon, IT and security teams rapidly focused on Zero Trust approaches to security to mitigate challenges of enabling secure remote work. Modern workplace employees are getting their work done any way they can these days – using personal devices, sharing data through new services, maxing out home WiFi, and collaborating outside the confines of traditional corporate network security. It has created an IT balancing act between security and WFH productivity.Read More
Secure access to email and other business productivity tools continues to be a top priority for IT administrators. Microsoft services, such as Azure Active Directory and Office 365, use OpenID Connect for authentication and OAuth 2.0 for authorization. Here’s how that process works: When Outlook connects to Exchange Online, the API requests are authorized using OAuth 2.0 Access Tokens. They are valid for one hour. When the tokens expire, the Outlook client is redirected back to Azure AD to refresh them. This provides an opportunity to re-evaluate policies for user access. If a user has been disabled in the directory or because of a Conditional Access policy, the admin might choose not to refresh the token.Read More
To say the cybersecurity community is a buzz over the recent news of the highly-sophisticated data breaches at many U.S. government agencies this month due to vulnerabilities in the SolarWinds Orion IT management platform is an understatement. Experts believe that Russian government hackers are behind this global espionage which may have started as early as last spring. The threat actors conducted a supply chain attack on SolarWinds Orion Platform with a backdoor through a FireEye software update. The SolarWinds versions impacted are 2019.4 HF 5, 2020.2 with no hotfix installed, and 2020.2 HF 1. Agencies affected include the Pentagon, the Department of Homeland Security and the Department of the Treasury.Read More
I haven’t met an organization yet that isn’t interested in saving money and optimizing their cloud spend. That’s where Azure Reserved Instances (RIs) come in. Properly leveraged, Reserved Instances, particularly Virtual Machine Reserved Instances can result in some significant savings. In fact, it was the topic of discussion at one of our recent Daymark Cloud Clinics where our technical cloud consultants offer free technical training and tips on a wide range of Azure and Office 365 features.Read More
