Do not optimize authentication for a majority portfolio in the cloud

 You can have an identity and access management tool, SIEM, CASB or single sign-on that was acquired in the local era and is now not the best option for your authentication needs for a predominantly cloud and remote access world. Be sure to take a look at these tools to ensure they can cover the type of cloud environment and your entire application portfolio that will protect your systems accordingly. For example, while CASBs are great at managing access to cloud applications, you may need one that works with your internal custom application, with risk-based authentication, or that protects you from more sophisticated and blended threats.

An outdated Active Directory

"Identity is now the new perimeter and data is flowing everywhere," said David Mahdi and Steve Riley of Gartner in a presentation. "You have to give the right people the right access to the right resources, at the right time and for the right reason." That's a lot of things to get right, for sure. This means that your Active Directory (AD) may not reflect reality, both from a list of current and authorized users and from current and authorized applications and servers. It's time to get your pruning shears. Migrating to the cloud will be smoother if you are migrating the most accurate information.

A Linux System Administrator takes care of computers running on the Linux operating systems. The professional will handle the support infrastructure, operating systems, virtual platforms, and applications. 

Do not seek help

Many managed security service providers (MSSPs) specialize in this type of migration, and you shouldn't be shy about asking them for help. You may be too busy to give your full attention to migration and ignore some important aspects unintentionally. Or in a hurry to move everything to the cloud, you left some back doors open or introduced vulnerabilities.

NoOps, the future of cloud computing

In 2009, consulting firm  Delloite  , curious about the trends that the beginning of  digital transformation  was causing in large companies and different sectors of the economy, created a study to survey the digital technologies employed at the time. Ten years later, the booming technologies in 2009 became obsolete  .  Regarding the maturity of  digital transformation  ,  Deloitte  says: “  To stay ahead of the market, organizations must work methodically to envision new innovations and possibilities, set their ambitions for the future and go beyond the digital frontier.” Sounds like a difficult task, doesn't it?  But not so much.  Many previous trends remain important today, have only been refined and continue to evolve.  These include analytics and  cloud computing  , for example. The use of  artificial intelligence  remains paramount, but it is now necessary to step in and completely re-...

How to identify and avoid false security alerts?

There are many security tools that tell us whether our system has been compromised by a variety of malware and what we can do to resolve this issue.

In this article we are going to show how we can do to recognize what we have mentioned and prevent it from happening to us. The problem of false security threats As we say, we can sometimes find messages that tell us that our device is infected with some kind of threat. They can tell us that we have viruses, that there is malware, or that we have some software that is spying on us. All of this can logically alert the victim. The important point here is that there are false security threats . These are messages that seek only to attract the attention of the user, who believes that he really has some variety of malware on his computer and...
