New OS X Tools for Photographers

If you’re into photography you’ll probably have tried all sorts of software tools in the quest for the perfect image. Over the years my favorite apps for managing, tweaking, and massaging images have been Adobe Lightroom and, when I want very specific results, Adobe Photoshop. The problem that I have had with Photoshop, in common with many other people, is that getting really good at correcting problems takes a lot of time and experience; Photoshop is not only complex but its features are so remarkably broad that photo editing becomes death by choices.Recently I’ve come across some software titles for OS X (macOS … whatever) that makes much of the power of Photoshop available in what you might consider pre-packaged forms for very reasonable prices. And, as we will see, some of the apps also operate as Photoshop plug-ins making serious photo editing easier.  To read this article in full or to leave a comment, please click here

Leaving it to the Last Second

Thanks to the moon, the earth's rate of rotation is slowing down. To compensate, we periodically adjust Universal Coordinated Time. On Saturday 31st December 2016, the last minute of 2016 will be extended to be 61 seconds long, creating the the timestamp 24:59:60. Previous leap seconds have not gone completely smoothly, and there is no particular reason to think that much will have changed for this leap second.

Non-malware attacks are on the rise

Security pros need to pay attention to malicious activities that don’t rely on actual malware to succeed, according to a study by Carbon Black.Attacks that exploited applications and processes legitimately running on systems – non-malware incidents – have risen from representing about 3% of all attacks in January to about 13% in November, the company’s “Non-malware attacks and ransomware take center stage in 2016” report says.“Non-malware attacks are at the highest levels we have seen and should be a major focus for security defenders during the coming year,” it says.The research included data from more than 1,000 Carbon Black customers that represent 2.5 million-plus endpoints. For measuring the non-malware attacks, the authors considered the malicious use of PowerShell and Windows Management Instrumentation were considered.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Five ways cybersecurity is nothing like the way Hollywood portrays it

According to pop culture’s portrayal of cybersecurity, the industry is hot property. Hacks and breaches not only dominate the real-world media, but they can be seen everywhere in TV and movies today.Granted, there have been some early examples of security issues playing a role in pop culture plot lines, such as the 1980s cult-classic Tron. But in recent years, Hollywood seems to have really picked up the mantle when it comes to cybersecurity. If the bright lights of TV and movies are to be believed, hackers are simultaneously the coolest and scariest people on the planet.Let’s take a look at five of the most common cybersecurity misperceptions as portrayed in TV shows and movies:To read this article in full or to leave a comment, please click here

Worth Reading: The new security normal

Today, the industry average time for finding an active attacker is about five months, reflecting the colossal failure of conventional security. The state of the union for federal security is that few if any non-defense agencies can find an active attacker on their network. Most cannot find a network intruder or a malicious insider, such as a rogue employee or contractor, working to steal or damage information or assets. Consider that the National Security Agency, the Office of Personnel Management and the FBI were breached along top security vendors and agencies. —MarketWatch

Monitoring Linux services

Mainstream Linux distributions have moved to systemd to manage daemons (e.g. httpd, sshd, etc.). The diagram illustrates how systemd runs each daemon within its own container so that it can maintain tight control of the daemon's resources.

This article describes how to use the open source Host sFlow agent to gather telemetry from daemons running under systemd.

Host sFlow systemd monitoring exports a standard set of metrics for each systemd service - the sFlow Host Structures extension defines metrics for Virtual Nodes (virtual machines, containers, etc.) that are used to export Xen, KVM, Docker, and Java resource usage. Exporting the standard metrics for systemd services provides interoperability with sFlow analyzers, allowing them to report on Linux services using existing virtual node monitoring capabilities.

While running daemons within containers helps systemd maintain control of the resources, it also provides a very useful abstraction for monitoring. For example, a single service (like the Apache web server) may consist of dozens of processes. Reporting on container level metrics abstracts away the per-process details and gives a view of the total resources consumed by the service. In addition, service metadata (like the service name) provides a useful way of identifying and grouping Continue reading
