Network security infrastructure provides several levels of protection to prevent MiM attacks:
The Cisco ASA Firewall and ASA security policies can protect filtering and ACL mode devices from malicious or unwanted applications by blocking incoming packet filters or ACLs, respectively. When using the Cisco ASA firewall to secure filtering and ACL mode devices, the user must be aware that it can occasionally fail to log in to the firewall (a known issue). For these cases, Cisco recommends using the Cisco ASA Config console to enable secure configuration for filtered and ACL mode devices.
For more information about how to configure the ASA firewall for secure configuration, visit ASA Configuration Secure Configuration, for more protection there are also other options like using a VPN, if you don’t know you can learn what is a VPN online.
You can learn here to connect to multiple clouds including Azure which has a capable suite of service offerings and works hard to integrate with private data centres in hybrid cloud environments.
In this article we will cover the following areas:
Application filtering: how to provide advanced access controls to Cisco ASA firewalls through firewall policy parameters,
Application configuration: how to use a separate virtual switch to create unused or outdated user connections through firewall policy configuration
Sample configuration file using a third virtual switch
To complete this tutorial, you will need to download the following:
- CA and Citrix Application Control CA supports several types of filtering and access controls.
- 2. 6. DS4 DS4 is a highly secure VoIP protocol that offers several levels of protection to filtering and ACL mode devices.
- 2. 6. DS5 DS5 offers a range of protocols including dialup and upgrade for network users, access to open and secure domains and it provides protection against many types of malware, including spam and phishing.
- 2. 6. LFP The Cisco ASA LFP firewall supports multi-frame filtering, multihoming and end-to-end isolation. A multihoming firewall offers security based on the type of protocol running through the firewall, not the device running the firewall.
- 2. 6. MX The Cisco ASA MX firewall is an advanced VPN access control solution. The ASA MX firewall provides end-to-end isolation in either WAN or LAN vias for IPsec traffic through firewall policy parameters and the Cisco MXIPsec software has several options to facilitate L3/L4 tunneling.
- 2. 6. FTP The Cisco ASA FTP firewall is an open source firewall solution that supports firewalls running Cisco ASA firewalls and is designed for faster internet deployment .FTP is like FTPS in that it encrypts data between two points and uses a plain text or PKCS #1/2 formatted transport. This allows users to download files quickly and keep them secure from viruses.
