This translates to a protocol that is friendlier to the battery life of mobile devices. This is where transformational services become cipher agility.

And in many cases it makes sense to connect a home video camera, baby monitor, alarm system, and thermostat to the Internet as well. The sum of these network-attached devices is called the Internet of Things IoT. IDC estimates that there will be 30 billion network-attached devices at the end of the decade.

These devices therefore require SSL for confidentiality. A subset of these SSL-enabled devices will use client certificates to identify themselves to the forwarding authority, which for many organizations will be their BIG-IP system. This is where SSL capacity will become a critical issue.

A successful product will produce hopefully millions of devices that will call home periodically. Experienced administrators know that the devices can become synchronized and call home at the same time e. This table can be used for capacity planning for a successful IoT product launch. A critical side effect of the confidentiality provided by the SSL protocol is that it can blind many network devices to the content of the traffic that the equipment is steering into the data center.

This problem needs to be foremost among the minds of network and security architects as they rebuild for an SSL-everywhere world. The solution to this problem, in general, is to be strategic about where the initial SSL decryption is taking place.

To maximize the efficacy of layer 7 security devices, the SSL decryption should be near the security perimeter. Once the inbound SSL has been decrypted, the resulting requests can be analyzed, modified, and steered. Policy-based traffic steering can be in-line with the web data or passive in the case of monitoring and reporting. A typical IPS excels at matching malicious traffic to thousands of signatures—but is not known for its SSL decryption performance.

When the IPS determines that a particular data source is sending malicious data, it can signal to the ADC that the source is not to be trusted for a period of time, perhaps 15 minutes. The ADC can then block that source address at the layer 3 firewall level, thereby saving the intrusion detection system IDS from having to monitor more of that traffic and saving the SSL compute cycles on the ADC as well.

The same approach can be applied to other in-line security technologies such as so-called next generation firewall NGFW devices, which are also known to struggle with SSL decryption. While the field of web analytics can encompass multiple subdomains, including security, it more commonly provides usability data for human interface designers.

By mapping how users interact with the website—where they linger and how they skip—web analytics provides an essential view into the workings of the website and allows administrators to quantify the value of changes.

Web analytics can be critical for revenue-generating web properties. Clearly, the data examined by web analytics must be decrypted prior to observation. Many customers with advanced security requirements usually financial must also re-encrypt data before as it leaves the application delivery controller tier further into the web servers.

To enable passive monitoring, a clone pool is configured on the ADC and a copy of the decrypted traffic is sent to the web analytics device. Clone pools can also be used to direct a copy of decrypted ingress traffic to an IDS. If it ever falls behind, the normal flow of traffic is not impeded since this matching is out of band.

For some organizations, this sort of best-effort, maximized-availability posture is sufficient. One of the benefits of the F5 SSL reference architecture is the level of programmability it offers. When the Heartbleed vulnerability struck the SSL community, information security personnel were rushed to protect systems.

For some, this meant scanning networks and preparing patches for hundreds or thousands of diverse virtual machines across multiple data centers and clouds. During those difficult initial days, administrators were aided by many hastily-crafted tools such open-source IDS signatures, Metasploit modules, and nmap plugins.

To assist these customers, within hours of the initial announcement, developers at F5 had provided two different iRules to mitigate Heartbleed—one for ingress traffic and the other for egress. The SSL Renegotiation attack was also initially mitigated by an iRule, as was documented by Vincent Bernat in a terrific analysis on the difficulty of mitigating cryptographic attacks. The iRule dropped any connection that attempted more than five renegotiations within 60 seconds. A new class of cryptographic attacks may be on the horizon.

While they have not been seen in the wild yet, there are already iRules prepared to mitigate them. The cryptographic processors at the heart of many ADCs are finding their way out of dedicated appliances and onto the network itself. These new network-attached devices still offload cryptographic operations from a controlling device; they simply perform that function across the network. Offloading in this fashion provides several benefits. It allows the architect to virtualize more of the infrastructure, including the device that was previously terminating the SSL, such as the ADC.

Another benefit is manageability. A natural function of the ADC in this environment will be to assist in the scaling up of the overall cryptographic load, since cryptographic offload devices can be loaded into a pool addressed by the virtual ADC. As the need for more cryptographic computation grows, more devices can be simply added to the pool, thereby boosting the scalability of the solution while bounding the cryptographic operations in hardware.

Clearly, the communication channel between the requesting device and the offload device must itself be protected usually via SSL , and most customers place it in a trusted part of the network as well. The chaos that ensued was ultimately too much for DigiNotar and the company imploded, leaving the Dutch government holding the bag. While the whole affair seems tragicomic in retrospect, a significant advancement resulted: the technique known as OCSP stapling.

These revocations are generally signed lists of revoked certificate serials numbers. Client software, such as a browsers or email readers, are supposed to double-check these certificate revocation lists by querying an online certificate status protocol OCSP server when they establish an SSL connection to a server. In practice, this almost never happens for two reasons: OCSP servers are often provisioned as an afterthought and outages are common. Even if the servers are available, the additional connection to the OCSP server may add latency significant enough to detract from the user experience.

The solution to all these problems is found in the OCSP stapling technique. This allows the client to receive and process the status message without having to incur the additional round-trip costs of a separate connection to the OCSP server itself. Problem solved. Ultimately it needs to be configured where the SSL is decrypted, and if that is at a central location, then the management surface is reduced to just that location.

F5 has offered integration with hardware security modules HSMs since the year These modules were developed specifically for ultra-high security environments where keys must not be compromised.

High performance of these cryptographic modules was usually not the point. The devices were also quite expensive, often costing 10x the price of the host computer.

The modules worked by allowing the hosting system to generate a key within the cryptographic device and then asking for information to be encrypted or decrypted with it. But the key itself could never pass through to the host in an unencrypted form.

The hardware security modules moved from the server to the ADC. Now they are moving to the cloud as network-attached standalone devices. As business moved to the Internet, commercial demand for these HSM devices grew rapidly.

As you build out or upgrade the campus network, here are three components to keep in mind. In a world more digitally connected than ever before, the performance of the underlying hardware is critical.

The EXC line card is designed for large campus distribution and core deployments, with 15 ports of GbE density.

Each of the GbE ports can be subdivided into 4 ports of 25 GbE using break-out cables. The EX line of modular switches provides a programmable, flexible and scalable core that delivers mission critical applications, while reducing cost and complexity with carrier-class reliability.

Network security should never come as an afterthought. It provides secure, encrypted communication to identify and prevent denial of service DoS threats and other intrusion attacks.

The newest EXC line card completes the secure campus, bringing higher density GbE and MACsec for exceptional flexibility, security and resiliency — meeting all of your needs for a scalable, end-to-end campus architecture.
