Three-quarters of U.S. CEOs in PwC’s 24th Annual Global CEO Survey said they are “extremely concerned” about cyber threats. They want to understand roadblocks, cyber insurance coverages, and budget allocation, among other critical topics. CISOs prefer the language of technology, and boards prefer the language of finance.
Editor’s note: This is Part 2 of a five-part cloud security series that will cover protecting an organization’s network perimeter, endpoints, application code, sensitive data, and service and user accounts from threats.
In this post, we’ll quickly cover the highlights of what you need to know about California’s Data Breach Notification Statute.
Cryptomining attacks are becoming more notable in-line with the rise of blockchain and cryptocurrencies, so detecting cryptomining has become a high priority. Security researchers have found data breaches related to various cryptominer binaries running within victims’ infrastructures. The default openness of Kubernetes clusters and the availability of the extensive compute power required for mining makes Kubernetes clusters a perfect target for cryptomining attacks.
In October 2022, a novel ransomware named Prestige was found targeting logistics and transportation sectors in Ukraine and Poland. According to Microsoft, victims affected by Prestige overlap with previous victims targeted by HermeticWiper, spotted in February 2022. The research also shows that the attackers deployed the ransomware within an hour between all victims, abusing highly privileged domain credentials to deploy the payload.
Database roles are similar to Windows groups — rather than revoking or granting access to each user separately, administrators manage access by granting or revoking permissions from roles and by changing role membership. Using roles makes it easier to accurately grant and revoke privileges for database users. And since multiple users can be members of a SQL database role, you can easily manage rights for a whole group of users at once.
Internal reconnaissance is one of the first steps an attacker will take once they have compromised a user or computer account in your network. Using various tools or scripts, they enumerate and collect information that will help them identify what assets they should try to compromise next to get what they want. For example, BloodHound will map out attack paths that can enable an adversary to escalate their privileges from ordinary user to admin.
Network File System (NFS) is an open standard for distributing a file system across a network for multi-client access. Designed in 1984, NFS has grown to include many authentication methods at both the share (export) and file system levels, including client IP/hostname, auth_sys (Unix auth), Kerberos and NFSv4.x ACLs. This blog post explains how to mount an NFS share on a Windows client.
Testing is a crucial best practice when developing software. Unit testing is one of the numerous strategies we can use to ensure our code is functional and optimal. As developers, we can code unit tests to check individual components (units) of the application code, such as a specific method. The idea is to write one or more unit tests for each code section and run them every time a change is made to catch defects as soon as they are introduced into the codebase.
