Cisco AnyConnect Secure Mobility Client : Posture module

What is AnyConnect Secure Mobility Client?

AnyConnect secure mobility client is basically a VPN access tool that provides additional security while allowing a connection to the remote network.

As AnyConnect supports two VPN protocols IPsec and SSH which provides more security. It has multiple modules that enhance its functionality, capabilities and security

There are two Posture modules in AnyConnect:

ISE Posture

HostScan

How ISE Posture works:

ISE Posture first does client evaluation against posture requirement policies, post that clients receive requirement policy from headend. They collect all required data and compare against policies and sends back results to anyconnect via headend.

Further AnyConnect evaluates whether endpoint is compliant or not. If the endpoint is compliant then the VPN connection can proceed.

Note:- here, headend could be either ASA (adaptive security appliance) or FTD firewall or ISE server.

Features of ISE Posture modules:
  • Posture checks
  • Necessary remediation
  • Reassessment of endpoint clients
  • Automatic compliance
Posture checks:

In this process, ISE posture module uses OPSWAT to perform posture checks. if endpoints fail to satisfy all mandatory requirements, it marks as non-compliant. network access will proceed only once the endpoint gets compliant.

Note:- OPSWAT (Omni-Platform Security with Access Technologies) is a security vendor that helps to protect from malware attack, provide secure data transfer and many more features.

Necessary remediation:

In this phase, We would see what has been detected and what needs to be done against policy. after that we will get “acceptable use policy notification” which should to be allowed to get access to the networks.

Patch management checks and remediations:

AnyConnect and Microsoft SCCM integrations provide patch management checks and patch management remediations. It checks critical patches in remote.

If it finds any missing patches then corrective action must be triggered for that. and post the successful completion of all the missing patches, patch management passes the check.

Reassessment of endpoint clients:

Post the endpoint is deemed compliant and is granted for network access. We have an option to do repeated reassessment to the remote hosts.

This posture check differs from initial posture checks, it allows the user to remediate if it configured as such. if it fails to meet the requirements, as a result the endpoint marks as non-compliant.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.

What are IoT devices?

The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.

Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.

How could your IoT devices be vulnerable?

When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.

When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.

Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.

The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.

Tips to secure your IoT devices

1. Change Default Router Name

Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.

2. Know your connected network and connected devices

If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.

3. Change default usernames and passwords

When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.

4. Manage strong, Unique passwords for your IoT devices and accounts

Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.

Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.

5. Do not use Public WI-FI Networks

Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.

6. Establish firewalls to discover the vulnerabilities

There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.

7. Reconfigure your device settings

Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.

8. Authenticate the IoT applications

Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.

9. Update the device software up to date

Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.

10. Track the smartphones and keep them safe

When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.

However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.

If you have any, feel free to share them in the comments! I’d love to know them.

Cisco Fixes High-Severity Webex, Security Camera Flaws

Cisco has issued patches for high-severity vulnerabilities plaguing its popular Webex video-conferencing system, its video surveillance IP cameras and its Identity Services Engine network administration product.

Overall, Cisco on Wednesday issued the three high-severity flaws along with 11 medium-severity vulnerabilities.

The most severe of these is a flaw (CVE-2020-3544) in Cisco’s Video Surveillance 8000 Series IP Cameras, which ranks 8.8 out of 10 on the CVSS scale.

“A vulnerability in the Cisco Discovery Protocol [CDP] implementation for Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to execute arbitrary code on an affected device or cause the device to reload,” according to Cisco’s security advisory.

The CDP is a network-discovery tool that helps network administrators identify neighboring Cisco devices. The vulnerability is due to missing checks when an IP camera processes a CDP packet.

To exploit the flaw, an attacker does not need to be authenticated. However, the person must be in the same broadcast domain as the affected device — because CDP is a Layer 2 protocol, attackers must be Layer 2-adjacent.

“An attacker could exploit this vulnerability by sending a malicious [CDP] packet to an affected device,” according to Cisco. “A successful exploit could allow the attacker to execute code on the affected IP camera or cause it to reload unexpectedly, resulting in a denial of service (DoS) condition.”

The vulnerability affects cameras running a firmware release earlier than Release 1.0.9-5 that have the CDP enabled, said Cisco. Of note, Cisco Video Surveillance 8000 Series IP Cameras are no longer being sold as of July 24; however, vulnerability and security support does not end until July 24, 2023.

Webex Bug

Cisco also patched a high-severity flaw affecting its Webex platform. This issue is severe given the troves of workforces turning to video conferencing systems during the pandemic – however, it is significantly complex to exploit, as an attacker would need to be both authenticated (needing valid credentials on the Windows system) and local.

The vulnerability stems from the incorrect handling of directory paths at run time. An attacker could exploit this vulnerability by placing a malicious DLL file in a specific location on the targeted system, which would then execute when the vulnerable application launches.

“A successful exploit could allow the attacker to execute arbitrary code on the targeted system with the privileges of another user’s account,” according to Cisco.

The flaw (CVE-2020-3535) affects Cisco Webex Teams for Windows releases 3.0.13464.0 through 3.0.16040.0; it does not affect Webex Teams for Android, Mac or iPhone and iPad.
