IPsec Overview: A secure network starts with a strong security policy that defines the freedom of access to information and dictates the deployment of security in the network. Cisco Systems offers many technology solutions for building a custom security solution for Internet, extranet, intranet, and remote access networks. These scalable solutions seamlessly interoperate to deploy enterprise-wide network security. Cisco System's IPsec delivers a key technology component for providing a total security solution. Cisco's IPsec offering provides privacy, integrity, and authenticity for transmitting sensitive information over the Internet. IPsec provides secure tunnels between two peers, such as two routers. You define which packets are considered sensitive and should be sent through these secure tunnels, and you define the parameters which should be used to protect these sensitive packets, by specifying characteristics of these tunnels. Then, when the IPsec peer sees such a sensitive packet, it sets up the appropriate secure tunnel and sends the packet through the tunnel to the remote peer. More accurately, these tunnels are sets of security associations (SAs) that are established between two IPsec peers. The security associations define which protocols and algorithms should be applied to sensitive packets, and also specify the keying material to be used by the two peers. Security associations are unidirectional and are established per security protocol (AH or ESP). With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.

Improving GRE stability | VPN Tunnels Part 3
 
07:43
Improving GRE stability | VPN Tunnels Part 3 Once you’ve built your GRE tunnel, you need to make sure it is stable. One of the potential issues that you may face is called Recursive Routing. This can cause your tunnel to flap repeatedly. Recursive Routing occurs when underlay routes are incorrectly advertised into the overlay. This can be worse when little attention is paid to LPM (Longest Prefix Match), the route metric, and the administrative distance. Another concern is the stateless nature of the tunnel. This can result in traffic being blackholed. We can use keepalives (heartbeats), as well as tuning the source and destination interfaces, in order to resolve this issue. There is a catch though. Keepalives do not work with route-based IPSec encryption. Neither does BFD for that matter! Some valid work arounds include using crypto-maps (policy-based encryption), using routing protocols, or using IP SLA with an EEM script. Part 1: How GRE Works - See the encapsulation process, as a packet moves from one side of the network to another Part 2: GRE Encryption with IPSec - GRE is not encrypted by default! See the basics of IPSec, and how we can use it with GRE tunnels Part 3: Improving GRE Stability - There are a few pitfalls to watch out for, including recursive routing. See some of the best practices that you can apply to make your tunnel stable For more information, have a look at https://networkdirection.net/Advanced+GRE Anatomy of GRE Tunnels (by ‘Sarah’): https://learningnetwork.cisco.com/blogs/vip-perspectives/2017/03/14/anatomy-of-gre-tunnels How to Detect IPSec GRE Tunnel Status: https://learningnetwork.cisco.com/message/590257#590257 This video is useful for Cisco #CCNA and #CCNP certifications 🌏 https://www.youtube.com/c/networkdirection 🌏 https://twitter.com/NetwrkDirection 🌏 https://www.patreon.com/NetworkDirection 🌏 https://www.facebook.com/networkdirection 🌏 https://www.networkdirection.net 🌏 https://www.patreon.com/NetworkDirection

28:05
more Cisco VPN Video at http://www.labminutes.com/video/sec/vpn The video walks you through configuring site-to-site (L2L) IPSec VPN tunnel between Cisco router and ASA firewall. This is probably the simplest form of L2L IPSec using 'crypto map' and crypto ACL to match interesting traffic. You will see that you can apply the same configuration thought process to both router and ASA, while ASA having slight variation on the use of Tunnel-group and Group-policy. We will also look at how to restrict traffic over the tunnel using an access-list (ACL). Topic includes - L2L IPSec VPN between Router and ASA - Restricting VPN Traffic with Per-Tunnel ACL

IPsec Overview: A secure network starts with a strong security policy that defines the freedom of access to information and dictates the deployment of security in the network. Cisco Systems offers many technology solutions for building a custom security solution for Internet, extranet, intranet, and remote access networks. These scalable solutions seamlessly interoperate to deploy enterprise-wide network security. Cisco System's IPsec delivers a key technology component for providing a total security solution. Cisco's IPsec offering provides privacy, integrity, and authenticity for transmitting sensitive information over the Internet. IPsec provides secure tunnels between two peers, such as two routers. You define which packets are considered sensitive and should be sent through these secure tunnels, and you define the parameters which should be used to protect these sensitive packets, by specifying characteristics of these tunnels. Then, when the IPsec peer sees such a sensitive packet, it sets up the appropriate secure tunnel and sends the packet through the tunnel to the remote peer. More accurately, these tunnels are sets of security associations (SAs) that are established between two IPsec peers. The security associations define which protocols and algorithms should be applied to sensitive packets, and also specify the keying material to be used by the two peers. Security associations are unidirectional and are established per security protocol (AH or ESP). With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.

Living in the Shadow of the Shadow Brokers - SANS DFIR Summit 2018
 
31:20
Most people know the Shadow Brokers leaked (supposedly) stolen NSA cyber tools, which lead to some of the most significant cyber security incidents of 2017. But in addition to targeting NSA, the Shadow Brokers have also targeted a few individuals in our community. Hear about the history of the Shadow Brokers and the implications of their actions for infosec and DFIR from one of the group’s targets. Have something you absolutely wanted to know about this great spy vs. spy saga, but were afraid to ask? This is your chance! Jake Williams (@MalwareJake), Senior Instructor, SANS Institute When a complex cyber attack put a private equity investment of more than $700 million on hold, the stakes couldn't have been higher. But that's exactly the kind of challenge that motivates Jake Williams, a computer science and information security expert, U.S. Army veteran, certified SANS instructor and co-author of FOR526: Memory Forensics In-Depth and FOR578: Cyber Threat Intelligence. To help mitigate the attack, Jake plied his information security expertise, discovered that not one but three different attackers had compromised the firm's network, and went about countering their moves. Jake relishes the idea of meeting adversaries on the cyber battlefield. "I went into this field because I wanted a challenge," he says. "Infosec is like a game of chess to me. The attacker plays their moves and you play yours." Jake started his information security career doing classified work with the U.S. government and was awarded the National Security Agency (NSA) Exceptional Civilian Service Award, which is given to fewer than 20 people annually. "I am immensely proud of the things I've accomplished," Jake says. "I'm positive the world is a safer place because of my work." Today, Jake runs a successful Infosec consultancy. He's been involved in high-profile public sector cases including the malware analysis for the 2015 cyber attack on the Ukraine power grid. He's also tackled a variety of cases in the private sector. In one, Jake discovered attackers compromising a custom service the client had distributed to all its endpoints. Leveraging experience and insight with advanced persistent threats helped Jake "think like the attacker" and determine the attacker's likely hiding spots.

DEF CON 24 - Alex Chapman and Paul Stone - Toxic Proxies: Bypassing HTTPS
 
44:57
Rogue access points provide attackers with powerful capabilities, but in 2016 modern privacy protections such as HTTPS Everywhere, free TLS certificates and HSTS are de-facto standards. Surely our encrypted traffic is now safe on the local coffee shop network? If not, my VPN will definitely protect me… right? In this talk we’ll reveal how recent improvements in online security and privacy can be undermined by decades old design flaws in obscure specifications. These design weakness can be exploited to intercept HTTPS URLs and proxy VPN tunneled traffic. We will demonstrate how a rogue access point or local network attacker can use these new techniques to bypass encryption, monitor your search history and take over your online accounts. No logos, no acronyms; this is not a theoretical crypto attack. We will show our techniques working on $30 hardware in under a minute. Online identity? Compromised. OAuth? Forget about it. Cloud file storage? Now we’re talking. Bio: Alex Chapman is a Principal Security Researcher at Context Information Security in the UK, where he performs vulnerability discovery, exploit development, bespoke protocol analysis and reverse engineering. He has been credited in security advisories for a number of major software products for vendors such as Citrix, Google, Mozilla and VMware, and has presented his research at security conferences around the world. He has spent the past several months making things (for a change), poking holes in old technologies, and pointing out security flaws which have no place in modern day software. Paul Stone is a Principal Security Researcher at Context Information Security in the UK where he performs vulnerability research, reverse engineering, and tool development. He has a focus on browser security and has reported a number of vulnerabilities in the major web browsers including Chrome, Internet Explorer, Firefox, and Safari. He has spoken at a number of Black Hat conferences, presenting the well-received ‘Pixel-Perfect Timing Attacks’ and ‘Next Generation Clickjacking’ talks. Paul’s recent obsession has been Bluetooth LE and has helped create the RaMBLE Android app for collecting and analyzing BLE data.
