If safety is a course of (and it’s), then it stands to motive that totally different initiatives (and contributors) are elsewhere. Some purposes have years of safety testing, with design completed by individuals who have labored in info safety for many years. Others are model new initiatives by builders engaged on their first open supply undertaking. It comes as no shock that Opensource.com’s high safety articles of 2019 symbolize this vary of expertise. We have articles that introduce fundamental safety practices in addition to deep dives into extra superior matters.
Whether you are studying the primary steps or wanting so as to add to your expertise acquired over a storied profession, there’s one thing for you within the high 10 safety articles of 2019.

Using GPG keys for SSH
Most individuals who use key-based authentication for SSH use SSH keys. And why would not you? It’s proper there within the identify. These are completely superb from a safety standpoint, however if you wish to make some types of key distribution and backup simpler, there’s one other method.

Graphically handle SSH keys with Seahorse
Using GPG for SSH keys is not everybody’s cup of tea, however that does not imply you are out of luck in the case of key administration. Seahorse is a graphical software for managing SSH keys (and different authentication strategies) that’s included within the GNOME desktop.

Security scanning your DevOps pipeline
Containers are in every single place as of late. But what’s in them? Knowing that containers meet your safety insurance policies is a vital a part of staying safe. Fortunately, you should use open supply instruments to assist automate compliance checking.

One of the good issues about cloud companies is that your information could be accessed from anyplace. One of the downsides to cloud companies is that your information could be accessed from anyplace. If you are utilizing “-as-a-Service” choices, you need to ensure that they’re securely configured. Anderson Silva, Alison Naylor, Travis McPeak, and Rich Monk be a part of forces to introduce 4 open source cloud security tools to assist enhance safety when utilizing GitHub and AWS. If you are on the lookout for by chance dedicated secrets and techniques—or attempting to forestall them from being dedicated within the first place—this text has instruments you should use.
How to make use of OpenSSL: hashes, digital signatures, and extra
Much of knowledge safety is predicated on math: particularly, the cryptographic features used to encrypt information and authenticate customers or file contents. After offering an introduction in Getting started with OpenSSL: Cryptography basics, Marty Kalin digs deeper into the main points of How to use OpenSSL: Hashes, digital signatures, and more, explaining how one can use the OpenSSL utility to discover these generally used however uncommonly understood ideas.
Learn about laptop safety with the Raspberry Pi and Kali Linux
Cheap hardware and open supply software program make a fantastic mixture, particularly for folks seeking to be taught by doing. In this text, Anderson Silva introduces the security-oriented Kali Linux distribution in Learn about computer security with the Raspberry Pi and Kali Linux. It’s a brief article, however it’s filled with helpful hyperlinks to documentation and security-related initiatives that you should use with your personal Raspberry Pi.
Will quantum computing break safety?
Has the remainder of this text been a waste? Will quantum computing render all the things we find out about safety out of date? The excellent news is that the reply is “no,” however quantum computing can nonetheless have a profound impression on safety and the computing world extra broadly. In Will quantum computing break security? Mike Bursell examines its potential impacts—each the excellent news and the dangerous. And after all, quantum computing might make it simpler to interrupt encryption, however that does not matter if the baddies cannot get your information within the first place.
Looking to 2020
Security will all the time be essential, and (because the quantum computing article suggests) the following few years will probably be an fascinating time within the area. In 2020, Opensource.com articles will take a look at the forefront of open supply safety and assist clarify the fundamentals to the ever-growing open supply neighborhood. If you’ve a subject you need us to cowl, please share it within the feedback, or—higher but— if in case you have an article in thoughts, write for us.
