Penetration testing for your organization has never been easier.

Reback council offers a simple, easy-to-understand suite of penetration testing services to commercial organizations throughout the India. Reback council is a commercial product offering of Chameleon Integrated Services, and can demonstrate a strong track record of IT security systems past performance that includes work for the Indian government and a diverse group of commercial customers (small and large).

We make the process of executing the most critical elements of penetration testing available in an easy to implement and easy to afford manner. We offer four separate services individually and as a bundle, that we believe are critical to establishing IT system security for your organization.

Our service offerings include:

Internal Penetration Testing
External Penetration Testing
Wireless Penetration Testing
Spear Phishing Campaigns

These services can be performed quickly and easily by our team anywhere in the India. Reback council uses top pen. testing experts from across the India to implement our security procedures. You can rest-assured that all work performed will be completed by a verifiable and accredited IT security expert. Additionally, all of our service offerings include deliverables and reports following all of our security protocols.

HORNET is New Tor-like Anonymity Network With Superfast Speeds

The Deep Web is a place that is hidden from the ordinary world because the browsers used to access the Deep Web, continuously encrypt user data. Due to this constant data encryption, the browsing speeds are slow. Our beloved Tor network has more than 2 million daily users that slow down its performance. To counter this speed issue, five researchers have developed a new Tor-style anonymity network called HORNET: High-Speed Onion Routing at Network Layer.  

Compared to anonymity networks like Tor, the HORNET system is more resistant to attacks and it delivers faster node speeds. The researcher team writes, “unlike other onion routing implementations, HORNET routers do not keep per-flow state or perform computationally expensive operations for data forwarding, allowing the system to scale as new clients are added.”

This paper “Hornet: High-Speed Onion Routing at Network Layer” was written by researchers Chen Chen of Carnegie Mellon University, along with David Barrera, Enrico Asoni, and Adrian Perrig of Zurich’s Federal Institute of Technology, and George Danezis from University College of London. Here’s the research paper.

To achieve speeds higher than Tor, HORNET doesn’t encrypt data as often- instead it encrypts just the personal stuff. In Tor, anonymity comes at the price of speed. To provide anonymity, Tor takes data and passes it through series of computers before the final destination. Each time, it passes from one computer to the other, the encryption exists and IP addresses change. Thus, it forms a time-taking multilayer network (hence “The Onion Router”).

HORNET nodes process the anonymous traffic at more than 93Gb/s speed.

The basic architecture of Tor and HORNET is same(onion routing). HORNET creates an encryption key set along with the routing info (connection state) on your system. Thus, the intermediate nodes don’t need to build this information each time, as these keys and connection state info is carried within packet headers (anonymous header or AHDR).

According to the research paper, it makes the whole system more secure as the other intermediate computers don’t waste time playing with the sender’s and receiver’s packets. Thus, the whole process becomes more fast and secure.

It is worth mentioning that HORNET is not yet tested at a large scale, it’s just these 5 researchers. Thus, extensive peer review is needed to adopt systems like HORNET.

Top 10 safe computing TIPS

1.Patch, Patch, PATCH!
Set up your computer for automatic software and operating system updates. An unpatched machine is more likely to have software vulnerabilities that can be exploited.

2.Install protective software.
Sophos is available as a free download for Windows, Macintosh, and Linux from IS&T's software page. When installed, the software should be set to scan your files and update your virus definitions on a regular basis.

3.Choose strong passwords.
Choose strong passwords with letters, numbers, and special characters to create a mental image or an acronym that is easy for you to remember. Create a different password for each important account, and change passwords regularly.

4.Backup, Backup, BACKUP!
Backing up your machine regularly can protect you from the unexpected. Keep a few months' worth of backups and make sure the files can be retrieved if needed. Learn more about TSM and how to backup your system.

5.Control access to your machine.
Don't leave your computer in an unsecured area, or unattended and logged on, especially in public places - including Athena clusters and Quickstations. The physical security of your machine is just as important as its technical security.

6.Use email and the Internet safely.
Ignore unsolicited emails, and be wary of attachments, links and forms in emails that come from people you don't know, or which seem "phishy." Avoid untrustworthy (often free) downloads from freeware or shareware sites. Learn more about spam filtering.

7.Use secure connections.
When connected to the Internet, your data can be vulnerable while in transit. Use remote connectivity and secure file transfer options when off campus.

8.Protect sensitive data.
Reduce the risk of identity theft. Securely remove sensitive data files from your hard drive, which is also recommended when recycling or repurposing your computer. Use the encryption tools built into your operating system to protect sensitive files you need to retain.

9.Use desktop firewalls.
Macintosh and Windows computers have basic desktop firewalls as part of their operating systems. When set up properly, these firewalls protect your computer files from being scanned.

10.Most importantly, stay informed.
Stay current with the latest developments for Windows, Macintosh Linux, and Unix systems.
