How (and why) to customize the Windows 10 Start menu

Opening Windows 8 for the first time and, gulp, not finding a Start menu had a lot of us tech-types sweating; ordinary users were dismayed and annoyed. We thank you so very much, Microsoft, for bringing it back in Windows 10 — and making even better.To read this article in full or to leave a comment, please click here(Insider Story)

IDG Contributor Network: Hello, world: Welcome to the agile data center

Some of the best technology in the world has begun with a simple "Hello World." I wanted to do the same and introduce myself, along with this new blog entitled "The Agile Data Center." With this blog, I will focus on some of the latest technologies around modernizing data center software and hardware, as well as aligning skill sets and introducing new roles in the IT space. So, what defines an agile data center and why should you care? Growing up in the technology space, I've worked for companies such as VERITAS, Symantec, SAP and EMC. During that time, and especially now, I can see and realize that most companies have not aligned business and IT. While this has "worked" for a number of years, companies are now becoming quickly disrupted by startups that have successfully aligned IT and can keep up with the rapid pace of business.To read this article in full or to leave a comment, please click here

Physical Security in a Virtual World – NSX Securing “Anywhere”

This is the second blog post in our Micro-segmentation Defined – NSX Securing “Anywhere” blog series. This blog post walks through security requirements that exist in environments with mixed workload deployment types. A mixed workload environment is one utilizing multiple application deployment models, including applications deployed on both virtual machines and legacy physical servers. We demonstrate how the necessary security requirements for mixed workload environments can be met through using VMware NSX as a platform for micro-segmentation and advanced security services. This blog focuses on the following:

1. Defining security requirements based on application deployment model or environment type
2. Understanding methods of protection in modern data centers
3. How NSX provides micro-segmentation for both physical and virtual workloads
4. How integration with ecosystem security and network controls functions

Security Requirements Differ in Heterogeneous Environments

Due to the evolving threat landscape and growing sophistication of cyber-attacks and threat actors, a single static policy or blanket approach to securing modern data centers is no longer adequate. These types of policies are difficult to manage and take a narrow-focused approach to what needs to be a much broader solution. Today’s private cloud environments are comprised of a variety of workloads and deployment models, whether it be Continue reading

Apstra comes out of stealth, solves the multi-vendor SDN challenge

Earlier this month I wrote a post asking the question: “Who speaks for multi-vendor environments?” Since then, I’ve had a few vendors reach out to me about their solutions that could indeed meet the needs of a vendor-agnostic data center. One of the most interesting, Apstra, came out of stealth mode this week and has a solution that’s certainly up to the challenge that I laid out in my blog.Apstra’s solution automates the data center operations across the lifecycle of the network—from the design/build phase through deployment/operate. The Apstra Operating System (AOS) takes an integrated approach to managing the data center that starts with business intent and is fed into a closed loop system. The data center operator then selects a pre-configured, and a validated template applies any constraints to it, which creates a blueprint for deployment.To read this article in full or to leave a comment, please click here

Is Apstra SDN? Same idea, different angle

One of the main goals of SDN (software-defined networking) is to make networks more agile to meet the changing demands of applications. A new Silicon Valley startup, Apstra, says it has an easier way to do the same thing. Rather than control the guts of individual network devices through software that makes them more programmable, Apstra says it can deal with those devices as they are and shape the network from a higher level. The result is a new approach that might let IT departments bypass some of the complex technologies and politics of SDN and still make their networks more responsive to users’ needs. It's due to go on sale by August.To read this article in full or to leave a comment, please click here

phpipam API clients

To simplify API calls etc. I created a separate GitHub repository to have a collection of phpipam API clients for different languages etc. If you created a client and want to share it head over to https://github.com/phpipam/phpipam-api-clients and share yours !

To start I created a php class to work as API client, now available in repo in php-client folder.
https://github.com/phpipam/phpipam-api-clients/tree/master/php-client

It supports all API calls, also encrypted requests are supported by setting $api_key variable in config file. Supported output formats are json/xml/array/object.

Here is a short example of working with client.

1. Copy config.dist.php to config.php and enter details for you installation / API to provided variables. You can also specify each parameter when initialising client directly.
2. Make calls

Here is a short example how to get details for specific section:
<?php
include config file and api client class file
require("api-config.php");
require("class.phpipam-api.php");

# init object with settings from config file or specify your own
$API = new phpipam_api_client ($api_url, $api_app_id, $api_key, $api_username, $api_password, $result_format);
# debug - output curl headers it some problems occur
$API->set_debug (false);
# execute call
$API->execute ("GET", "sections", array(5), "", $token_file);
# ger result
$result = $API->get_result();

Forensic Lab Game Zero – Level 2 Results

Below are my solutions to the level 2 of the forensics lab game zero. The solutions to  the level 1 of the game are posted here.

1. Find way to reset root's account password and retrieve flag from /root/flag.txt

Reboot the VM and press 'e ' edit inside the Grub menu screen. Add command init=/bin/bash at the end of the line starting with linux and press F10. Thne mount file system as read-write.

root@(none):/# mount -n -o remount,rw /

Change password for user root.
root@(none):/# passwd

root@(none):/# cat /root/flag.txt
8d55761dfafe912daa2fa6c38e05435093f7f636

root@(none):/# echo -n '8d55761dfafe912daa2fa6c38e05435093f7f636' | sha1sum
0166bc38c1165d0ba783ea722b84ed3a0d2547f8

Restart the virtual machine and switch to the root account.

2. There is a memory dump of the windows machine is stored in file /root/memdump.mem. Find the flag among commands executed on that machine

Find info about our memory dump with imageinfo plugin.

root@debian1989:/home/kassad# python /opt/tools/volatility-2.4/vol.py imageinfo -f /root/memdump.mem | grep Profile
Volatility Foundation Volatility Framework 2.4
Suggested Profile(s) : Win7SP0x86, Win7SP1x86

To avoid typing chosen profile --profile=Win7SP1x86 every time vol.py is called, export the profile.

root@debian1989:/home/kassad# export VOLATILITY_PROFILE=Win7SP1x86

To avoid typing path to memory dump file, export memory dump location so you do not need to add argument -f Continue reading

HPC Spending Outpaces The IT Market, And Will Continue To

Sales of HPC systems were a lot brisker in 2015 than anticipated, and according to the latest prognostications from the market researchers at IDC presented from the International Supercomputing Conference in Frankfurt, Germany this week, growth in the HPC sector will continue to outpace that of the overall IT market for many years to come.

In a sense, the good numbers that the HPC market turned in last year are perhaps a little undercounted. In his traditional early morning breakfast briefing at the conference, Earl Joseph, program vice president for high performance computing at IDC, said that he had been …

Microsoft invokes Supreme Court opinion in Ireland email case

Microsoft believes its refusal to turn over email held in Ireland to the U.S. government got a boost from an opinion of the Supreme Court on Monday, which upheld that U.S. laws cannot apply extraterritorially unless Congress has explicitly provided for it.In a decision Monday in a separate case on the extraterritorial application of a provision of the Racketeer Influenced and Corrupt Organizations Act (RICO), the Supreme Court set out the ground rules for its analysis, pointing out that “absent clearly expressed congressional intent to the contrary, federal laws will be construed to have only domestic application.” The court was applying a canon of statutory construction known as the presumption against extraterritoriality.To read this article in full or to leave a comment, please click here

Directed ARP Saga Continues

Reading my Directed ARP and ICMP Redirects blog post you might have wondered “how did Directed ARP ever get into ***redacted***?”

I searched for “directed ARP cisco” and found this gem, which really talks about unicast ARP behavior, an ancient mechanism documented in RFC 1122 (it’s not my Google-Fu, I got the reference to RFC 1122 in this blog post).
