Heartbleed is a critical bug in OpenSSL that allows attackers to read portions of an affected server's memory. It impacts OpenSSL versions 1.0.1 and 1.0.2. The bug is in the OpenSSL implementation of the TLS/DTLS heartbeat extension, which is supposed to keep connections alive but can be exploited to read server memory. This allows attackers to eavesdrop on encrypted communications, access sensitive server data like passwords, and impersonate users and services. The fix is to upgrade OpenSSL and change passwords for affected websites and services.

The Heartbleed Bug
The document discusses the Heartbleed bug, which was a vulnerability in the OpenSSL implementation of the TLS/SSL protocols. The bug allowed attackers to read portions of servers' memory, potentially leaking sensitive data like private keys and passwords. It was discovered in 2014 by a team at Codenomicon and Neel Mehta of Google. Around 17.5% of SSL-enabled sites were affected. To protect against attacks, system administrators were advised to remove the vulnerable OpenSSL heartbeat extension, upgrade to a patched version, and revoke old key pairs and force password changes.

Basic introduction to HTTP/2, and how it can help to speed up SAP Fiori applications. Presented at the 2017 SAP Inside Track Silicon Valley #sitSV, and at SAP TechEd in Las Vegas as session NET52433.
Let's use modern protocols everywhere!
HTTP/1.1 is an obsolete and inefficient protocol for web communication. HTTP/2 provides major improvements such as header compression, multiplexing of requests and responses, and server push that can reduce webpage loading times by over 50%. HTTP/3 is expected in 2019 and will replace TCP with the UDP-based QUIC protocol, addressing limitations of TCP like head-of-line blocking and allowing for faster 0-RTT connections. Organizations should adopt HTTP/2 now and prepare for HTTP/3 to improve performance of their web applications and infrastructure.

PLAYBACK: A TLS 1.3 STORY
Secure communications are one of the most important topics in information security, and the Transport Layer Security (TLS) protocol is currently the most used protocol to provide secure communications on the internet. For example, when you are connecting to your online banking application, your favorite instant message application or social networks, all those communications are being transmitted using TLS. With TLS, the information sent by the browser and the service is secured and encrypted, meaning that the information cannot be modified or tampered with by an attacker. The communications are also verified to ensure that the browser is connected to the right endpoint (e.g. Wikipedia).
Presentation, called “Playback: A TLS 1.3 Story,” about some of the known security implications of using 0-RTT and will show proof of concepts of some attacks that have been seen in real-world environments. Attendees will learn about TLS 1.3 0-RTT, see some examples about how an attacker could take advantage of that new feature and get an understanding of the security implications of enabling the feature and how it could be used safely minimizing any potential security impacts.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Heartbleed
- 2. “Catastrophic is the right word. On the scale of 1 to 10, this is an 11.” --Bruce Shneier
- 3. What is Heartbleed? O What is Hearbleed? O It is a critical bug in the OpenSSL’s implementation of the TLS/DTLS heartbeat extension that allows attackers to read portions of the affected server’s memory. O What is OpenSSL?! O It is open source software that is used by Apache and Nginx webservers, 66% Market share to do encryption through the Internet O Affected Versions: OpenSSL 1.0.1 and 1.0.2
- 6. What is Heartbleed O What is Heartbeat ?? 1- Used to keep connection Alive 2- Client Sends data to the Server, server echoes it back 3-Similar to ICMP ping but within HTTP Web Server Running OpenSSL Client Heartbeat “Hello” 6 Heartbeat “Hello” 6
- 9. Heartbleed Explained O Non Technical O Ask for 100-photo box O Seller doesn’t know how to count O Two scenarios O Actual 100-photos O Only 1 photo
- 10. Heartbleed Explained O Technical: “memcpy(bp, p1, payload);” Actual BUG :( void * memcpy ( void * destination, const void * source, size_t num ); O The function does not check for any terminating null character in source - it always copies exactly num bytes. O To avoid overflows, the size of the arrays pointed by both the destination and source parameters, shall be at least num bytes, and should not overlap (for overlapping memory blocks, memmove is a safer approach).
- 11. Heart bleed - explanation 11
- 12. Heart bleed - explanation 12
- 14. Heartbleed Impact O Eavesdrop on encrypted communication O Get access to sensitive data in the memory O Impersonate users and services
- 15. Heartbleed fix O Server-Side • Quick fix: Disable heartbeats • Real fix: Upgrade OpenSSL • User Actions: • Change your passwords !! • Test Sites yourself
- 16. Heartbleed - PoC O https://blog.bugcrowd.com/heartbleed- exploit-yet/
