Cisco to invest in Israeli Cyber Security Technologies

http://www.haaretz.com/polopoly_fs/1.554685.1391082316!/image/621043262.jpg_gen/derivatives/landscape_640/621043262.jpg

Cisco is enhancing its presence in Israel. Bryan Palma, Senior Vice President of Security Services of Cisco Systems announced this week that his company will invest tens of millions of dollars in Israeli venture capital fund, JVP. Fund information security the JVP is expected to raise a total of $ 120 million within the next few months.

"Israel is very important for Cisco. Cisco CEO John Chambers is personally committed to making Israel the first country in digital. We are working closely with the government and we are very excited about the work we are doing through education and health and cyber. Particularly in the IT sector, which is the area I am responsible. There are a couple of important things that we are doing here in Israel. The first is that we are hiring security consultants to join our team, because we know that there is great talent. Secondly, we are working with the government and start- ups to create a cyber - lab that will help advance the profession of computer security. The final one is really our strategic investment that we have made with the JVP. We think it's important to continue to invest here in Israel and we will continue to do so in computer and really make Israel become the nation's first digital,

The fund in which Cisco is set to invest is the seventh of the JVP, according to the filing with the SEC by the end of two months ago, signed by the general partners of the JVP; JVP said the new fund will invest in its core business: digital media, technology, cyber security and storage.
According to the JVP, " since the fund was founded in 1993 by (Labour Party), the JVP has invested about a billion dollars is about 100 companies, and has led to significant outputs 26." The new fund will increase the capital managed by the JVP to more than a billion dollars. JVP also has two technology incubators, investing in early stage companies - JVP Media Labs, run by JVP and Cyber Laboratories Beer Sheba.

Cisco is one of the most active multinational tech companies in Israel. The company, which develops equipment for IP-based networks for large organizations and telecommunications, has a large R & D center in Netanya. It also owns NDS, which has acquired in early 2012 for $ 5 billion. Cisco is the leading supplier of IBC, the communication initiative of Israel Electric Company. Cisco has granted credit 'initiative of more than $ 140 million, about 10% of the initial investment. Last November, Cisco has won a major tender of the Ministry of Defense to develop the network IP address of the IDF for over $ 150 million.

Cisco Security Group Access An Introduction

The concept of identity-based access network - in essence, provide the credentials to log on to a network or a resource - not a new phenomenon. Over the years , it has evolved from access to individual applications for single sign-on (SSO ) and centralized user record using multiple authentication methods and authorization policies apply custom user group , type of access and the access method.

Basically, IBNA is giving a confidence level of a user or device based on an identity document . Security within an organization is based on control , enforcement and predictability . The more you know about the users of the network - individuals or devices - the most comprehensive and effective security policy will be. Implement IBNA is a great way for organizations to review their network design, secure and optimize asks questions like :" Where does and why" "Who are you "and Understanding the flow of the network and the user resource requirements is the basis for the Cisco Access Security Group (ASG ), which falls under the umbrella of the Cisco TrustSec . SGA offers several advantages:


1) Grants network resource access based on identity and associated policy.
2) Enhances security and control as traffic flows are more easily segmented.
3) Reduces the cost and complexity associated with large firewall policies and access-list rules.
4) Provides a mechanism for consistent and dynamic policy propagation across different platforms.
5) Enables centralized policy management and auditing per identity.

SGA is based on the concept of assigning a user a security group tag (SGT) . The SGT is a 16-bit value is inserted into a frame 802.1AE. SGT Assignment known as classification. When a user is authenticated using 802.1X, MAC Authentication Bypass (MAB) or Web Authentication ( WebAuth ) , SWG is assigned as part of the authorization policy in the AAA server, usually Cisco Identity Services Engine ( ISE).In addition, network resources, such as infrastructure devices (routers, switches, firewalls, wireless LAN controllers ( WLCs ) and SGT services are also assigned. Tags can also be set manually from the port level or statically assigned addresses IP , subnet or VLAN in the individual network devices.

SGA is based on the propagation of EPG information devices that become points of policy implementation. Propagation of the EST can be done online by the special hardware to label each traffic flow with a user assigned SGT ASIC. The integrated value is carried out with the flow and examined from the point of execution.

For devices that do not have the capacity to handle the embedded SGT, tag information can spread through SGT Exchange Protocol ( SXP ), which is a TCP - to-peer network in which the "speaker " IP address propagates SGT binding information to a " listener. " The listener can use this information to apply policies based on the learned values SGT. While the user traffic passes through a point of the application is given the SGT should be allowed for security ACL group that was downloaded from the centralized policy store (ISE) or statically configured on performance the device.


Policies SGACLs simplify and reduce the complexity rule, as shown by the simple example below.
In general, due to the syntax used to create rules based on IP address:
(# Of Sources) * (number of positions) * permissions = # of ACE (access control entries).
Thus four subnets that require access to three Web servers using HTTP and HTTPS require:

4 * 3 * 2 = 24 ACEs.

Using SGTs, we can assign all the "users" in each sub-net to a group (source), and combine the three Web servers in a protected group (destination), and then apply the two permits (permit HTTP, HTTPS permit) plus the catch -all the actions for the non-conforming traffic:

1 * 1 * 3 = 3 ACEs.

Obviously, the more granular SWG allocation, more rules, but the concept is the use of TMS provides more efficient and rational grouping of resources based on the role and function.

Consistent application of policy information SGT multiplication is obtained and applied devices have consistent policies throughout the network topology. More centralized policy management and more devices that can be downloaded dynamically a set of rules apply , the lower the possibility of configuration errors arising from the management of a large number of ACE statically defined multiple network devices.

Migrating to an EMS solution can be done gradually. Start with the classification and propagation of SGT between Cisco devices. SXP, which uses TCP as transport, tags allow propagation of all devices in the non-SGA level. This will facilitate the introduction of running on network devices such as switches strategic access to WLC and the edge of the network and the protection of critical resources such as the Nexus switches in the core.
