Those who are still using the traditional ASA CX Context-Aware Security, Cisco Prime Security Manager and Cisco ASA Intrusion Prevention System are advised to migrate towards to Cisco ASA 5500-X and 5585-X with FirePOWER Services. These ASA bundles are capable of delivering the power of ASA firewall with Sourcefire threat and advanced malware protection. Cisco is trying to capitalize on the these three things to make there mark in Next Generation Firewall market segment. Also Cisco is replacing the Cisco Prime Security with Cisco FireSIGHT Management Centre to mange the new ASA 5500 –X and 5585-X Appliances.

Juniper Network claims, with addition of new hardware updates for the Juniper Networks® SRX5800 Services Gateway makes it’s the industry’s fastest firewall. According to latest press release by Juniper, the Juniper Networks® SRX5800 Services Gateway is capable of delivering Internet Mix (IMIX) firewall throughput up to 2 Terabits per second (2 Tbps).

Juniper added third-generation input/output cards, an enhanced midplane chassis and third-generation system control boards – to the SRX5800. The input/output card supports two packet-forwarding engines (PFE), a high-density configuration of 2×100 GbE and 4×10 Gbe high speed interfaces. The third-generation input/output card is capable of delivering 240 Gbps of bandwidth, double the bandwidth of the previous hardware card.

“As the threat landscape continues to evolve and a variety of devices increasingly flood the network, companies are forced to not only meet network performance demands but also ensure they have efficient, fast and scalable protection in place,” said Christopher Hoff, vice president and security CTO at Juniper Networks.

Well I believe these new announcement will certainly create healthy competition in the service provider market segment, and this is going to benefit large enterprises and service providers in long run.

Cisco Iron Port ESA doesn’t support Tacacs+ Authentication

The other day I was integrating Cisco Iron Port ESA with Cisco ACS Server for AAA, I was thinking of utilizing Cisco’s power Tacacs+ protocol, to my surprise Cisco Iron Port ESA doesn’t support Tacacs+. The only option available is radius and it does not provide the granularity and control over the Cisco Iron Port ESA.

ESA_large

After Cisco acquiring Iron Port in 2007, I thought Cisco will further enhance this product and include Tacacs+ features but unfortunately they failed to do so. Being a very powerful email gateway Iron Port offers great features in terms of Anti Spam, Email filtering, email redirection and many reach features, which are customizable as well.

Also there is no proper documentation on how to integrate Cisco Iron Port ESA with Cisco ACS Server.

These questions are designed to validate how a Service Provider Professional is capable of designing; implementing, diagnosing and troubleshooting complex Service providers network infrastructures and services based on dual stack solutions (IPv4 and IPv6).

The Cisco CCIE® Service Provider Written Exam (400-201) covers following 6 domains

  1. Service Provider Architecture and Evolution
  2. Core Routing
  3. Service Provider Based Services
  4. Access and Aggregation
  5. High Availability and Fast Convergence
  6. Service Provider Security, Service Provider Operation and Management

Since a dedicated title from Cisco Press is not yet released, following Cisco Press titles can be used as the reference for the preparations of the CCIE® Service Provider Written Exam (400-201)

IP Routing on Cisco IOS, IOS XE, and IOS XR: An Essential Guide to Understanding and Implementing IP Routing Protocols

MPLS Configuration on Cisco IOS Software

Cisco Live presentations are also great resources for the preparations; you can find more details about them on the INE CCIE Service Provider v4 Kickoff classes. If you have an access INE All Access Pass you can watch those videos or attend the class live on line.

Other day I was attending the Online CCIE Community event organized by Cisco Systems, the event was hosted by Jeanne Beliveau-Dunn, Vice President and General Manager of Learning@Cisco and there were two amazing speakers

  • Dave Mallory, Chief Technology Officer, Learning@Cisco, CCIE
  • Yusuf Bhaji, Senior Manager, Global Certifications, CCIE

According to Yusuf Bhaji, Cisco will integrate SDN into all of the CCIE Certifications tracks.

Since a new version of CCIE Service Provider is available from the third week of May, all the CCIE aspirers will experience the SDN in CCIE Service Provider exam in form of Cisco Evolved Programmable Network ( e.g. ASR1k/9K, ME3600, etc)

Cisco is also considering to add Cisco ACI ( eg Nexus 9k, AVS) in the next revision of CCIE Data Centre.

However tracks like CCIE R&S, CCIE Security, CCIE Wireless and CCDE will be aligned with Cisco APIC-EM, Open SDN Controllers, WRL Controllers and the SDN content is expected to be included in next revision. Still the dates or the time lines are not known.

I believe it’s a good time for Networking professional to focus on SDN, start mastering scripting languages like Python. For certain SDN and Network programing is going to emerge and those who are already skilled with these skill sets can be seen in more demand.

According to the recently released Gartner’s latest Magic Quadrant for Enterprise Network Firewalls report, Palo Alto Networks leads the Magic Quadrant for the fourth consecutive year. They share this honor only with checkpoint. I was expecting Cisco with their Fire power services would make some impact at the Enterprise market yet they failed.

Screen Shot 2015-04-24 at 6.15.33 PM

Palo Alto being an innovator into Next Generation Firewall certainly gave them the edge to lead. So far my experience with Palo Alto compared to their competitors in the Next Generation Firewall is far much better, I have experienced some of their competitors Next Generation Firewall fails miserably especially when we turn on the advance features like content filtering,  IPS and so on.

This is not the case with Palo Alto Networks next generation firewall. However Palo Alto have to invest on their training development program not only for their partners but also for Security Professionals who wants to excel on Palo Alto certifications.

We all know Palo Alto is making there mark when it comes to Next Generation firewalls and surpassing most of the leaders in the NG Firewall domain. The test report released clearly states that Palo Alto Networks PA-5020 was the only product that blocked 100% of the live exploits during NSS lab test. This kind of report certainly creates huge expectations from Palo Alto Networks and who knows they may dominate the Next Generation IPS domain.

Mr. Vikram Phatak, the CEO of NSS Labs says

Exploits being used by Threat Actors in active campaigns are the most likely source of compromise that enterprises face every day.  The Palo Alto Networks PA-5020 was the only product that blocked 100% of these live exploits during our test, and 98.8% against all exploits, earning a recommendation by NSS Labs for security effectiveness.

The complete report can be downloaded from the Palo Alto networks website. Lets wait and see who is going to dominate the NG IPS Segment in coming years.

The Palo Alto Networks researchers discovered this vulnerability and according them, this vulnerability triggers only when an Android app is either downloaded from any third party app store or when users clicks on the advertisements displayed by the app.

The summary published by Palo Alto is as follows

  • Android Installer Hijacking allows an attacker to modify or replace a seemingly benign Android app with malware, without user knowledge. This only affects applications downloaded from third-party app stores.
  • The malicious application can gain full access to a compromised device, including usernames, passwords, and sensitive data.
  • Palo Alto Networks worked with Google and major manufacturers such as Samsung and Amazon to inform them of the vulnerability and issue patches for their devices.

The suggestion from Palo Alto Networks is to install a vulnerability scanner, which Palo Alto Networks developed especially for this vulnerability.Pick up the free installer from the Google Play Store. The only way to avoid being affected by these kinds of vulnerabilities is to download the apps, which are available in Google Play Store.
