Your Network Has Left the Building – How do you secure it?

Your network has left the building. It’s no longer sitting in the server room down the hall where you can keep an eye on it. And it’s no longer safely tucked behind your corporate firewall. Instead, it’s in the cloud. It’s inside your users’ smartphones. And especially now, your corporate network is in people’s homes.

Today’s security teams have to mind various areas of their network and cloud infrastructure, remote users and endpoints, and applications running everywhere in order to remain secure. And as soon as new technology is developed or widely used, attackers find ways to take advantage of it – making security vigilance even more critical.

In our recent 2020 CISO Benchmark Study, we asked security professionals which areas of their environment they find most challenging to defend. According to the study:

  • 52% find mobile devices and data stored in the public cloud very or extremely challenging to defend
  • 50% find private cloud infrastructure very or extremely difficult to defend
  • 41% find data centers and network infrastructure very or extremely difficult to defend
  • 39% say they are really struggling to secure applications

While the moves to mobile and cloud seem to pose the biggest challenges, the data shows that the rest of your security concerns haven’t gone away either.

So how do you do it all?

How do you protect some of the newer technologies that have become part of your environment while still paying attention to things like your traditional data center and network infrastructure to make sure they are not breached? And how do you do this amidst unprecedented remote worker hurdles and a dramatic shortage of skilled cybersecurity professionals? Here are some examples of how Cisco can help you protect the challenge areas outlined above.

Mobile

In order for security to work, it has to work across all the devices your employees are using. Cisco’s endpoint security combines a variety of security technologies to make sure your users’ mobile devices are protected, and in turn, do not compromise the corporate network. For example, Cisco AnyConnect and Cisco Duo enable users to securely access your network or applications using managed or unmanaged, mobile or traditional devices. And Cisco Umbrella and Cisco AMP for Endpoints defend these devices against threats from the first line to the last line of defense.

In response to current challenges, we have also launched the Cisco Secure Remote Worker solution to help organizations address the recent rise in remote and mobile workers. The intent is to better enable IT and security teams to quickly provision remote workers without sacrificing cybersecurity. The offering includes extended free trials and expanded usage counts to help alleviate today’s tremendous IT and security demands. Learn more about how this offering can enable secure access for a distributed workforce and help you defend against malware across the network, endpoints, cloud, and applications.

Cloud

Cisco’s cloud security protects your assets and data in the cloud from multiple angles. It helps secure private, public, and hybrid clouds to facilitate your transition to a multicloud environment. With Cisco’s cloud edge security, you can: 1) secure cloud access, 2) protect cloud users, data, and applications, and 3) extend in-depth visibility and threat detection into the cloud.

Data Center

Today’s application workloads are more dynamic, moving across on-prem and multicloud environments. This requires a new strategy for data center security that can protect workloads wherever they go. The Cisco Secure Data Center solution provides several layers of security through in-depth visibility, segmentation, and threat protection. The solution brings together key technologies that let you see, segment, and secure your data as it travels across your environment and into the cloud.

Applications

Related to data center security is application security. Cisco’s application security brings continuous, adaptive protection closer to your applications to give you greater insight and control over what is running in your environment. The security follows your applications to ensure protection without hindering productivity and innovation. This allows you to understand application behaviors, automate micro-segmentation, and use security analytics to speed detection.

Network

Perhaps the trickiest area to summarize is network security due to the ever-expanding components that make up today’s “network.” You need a next-generation firewall that can keep up with your expanding infrastructure and sophisticated attackers. You need a way for authorized users to securely connect to the network. And once they’re logged in, you need multiple layers of protection to prevent them from abusing their privileges or being compromised by malware.

Bringing it all together

While we secure many areas of the corporate environment, we don’t do so in silos. Our security products all work together – and with the customer’s infrastructure, including third-party technologies – to provide more cohesive, automated defenses. By taking a platform approach to security, Cisco SecureX results in greater visibility, collaboration, and protection across all threat vectors, access points, and areas of your infrastructure. This reduces complexity while enabling a zero-trust security strategy.

Computer-Based Training: April 2020 Release in Review

As IT systems expand in their complexity, ensuring security diligence becomes increasingly challenging. More importantly, the need for job-specific guidance becomes critical for all those involved in the secure building and operating of them, whether in Program/Project Management and Acquisition, Network Services, Systems Architecture, Development, Risk Management, or even Threat Analysis. 

Security Threats Facing Modern Mobile Apps

We use mobile apps every day from a number of different developers, but do we ever stop to think about how much thought and effort went into the security of these apps?

It is believed that 1 out of every 36 mobile devices has been compromised by a mobile app security breach. And with more than 5 billion mobile devices globally, you do the math.

The news that a consumer-facing application or business has experienced a security breach is a story that breaks far too often. As of late, video conferencing apps like Zoom and Houseparty have been the centre of attention in the news cycle.

As apps continue to integrate into the everyday life of our users, we cannot wait for a breach to start considering the efficacy of our security measures. When users shop online, update their fitness training log, review a financial statement, or connect with a colleague over video, we are wielding their personal data and must do so responsibly.

Let’s cover some of the ways hackers access sensitive information and tips to prevent these hacks from happening to you.

The Authentication Problem

Authentication is the ability to reliably determine that the person trying to access a given account is the actual person who owns that account. One factor authentication would be accepting a username and password to authenticate a user, but as we know, people use the same insecure passwords and then reuse them for all their accounts.

If a hacker accesses a user’s username and password, even if through no fault of yours, they are able to access that user’s account information.

Although two-factor authentication (2FA) can feel superfluous at times, it is a simple way to protect user accounts from hackers.


2FA uses a secondary means of authenticating the user, such as sending a confirmation code to a mobile device or email address. This adds another layer of protection by making it more difficult for hackers to fake authentication. 

Consider using services that handle authentication securely and having users sign in with them. Google and Facebook, for example, are used by billions of people and they have had to solve authentication problems on a large scale.
Reverse Engineering

Reverse engineering is when hackers develop a clone of an app to get innocent people to download malware. How is this accomplished? All the hacker has to do is gain access to the source code. And if your team is not cautious with permissions and version control systems, a hacker can walk right in unannounced and gain access to the source code along with private environment variables.

One way to safeguard against this is to obfuscate code. Obfuscation and minification make the code less readable to hackers. That way, they’re unable to conduct reverse engineering on an app. You should also make sure your code is in a private repository, secret keys and variables are encrypted, and your team is aware of best practices.
