Endpoint security
Endpoint security involves protecting devices like laptops, smartphones and other endpoints that access a corporate network. It uses security software located on a server that authenticates login requests from endpoints and updates their software regularly. Endpoint security is becoming more important as employees use personal devices for work. It provides comprehensive protection from threats like malware, exploits, and data loss across email, web, applications and network activity through features like behavioral monitoring, intrusion prevention and alerts. While antivirus protects against viruses, endpoint security provides a broader solution that safeguards the entire network by securing each individual endpoint device.

Cyber security is not safety.
I've updated a talk I gave in 2010 to include the latest FDA guidance on mobile devices and cyber security. But really nothing has changed since then. Medical device vendors are still grappling with the notion that cyber security involves a complex, interconnected, rapidly changing landscape of vulnerabilities, threats, zero-day exploits, software security issues that does not fit the slow-moving pre-market approval and static risk analysis that FDA uses for safety.
In this presentation we show how to use a practical threat analysis methodology and present real-life examples of how to build a prioritized, cost-effective security countermeasure plan.
Killed by code 2015
So - guess what? Safety is not cyber security!
Managing cyber security for medical devices is a challenge for medical device vendors and regulatory consultants who are accustomed to estimating patient safety risk without having to explain and understand a complex, rapidly changing and interconnected environment of vulnerabilities, attackers, attacker entry points and zero-day threats.
In this updated version of a talk I gave 5 years ago - I show how to use threat modeling in order to provide a prioritized security countermeasure plan that will cost the medical device vendor the least amount of money and save him the grief of trying to deal with cyber threats in his safety risk analysis.

Discuss reaction strategies to handle Malware?
Solution
Malware:
Malware is a software that is dangerous, It can damage phone, desktop or tablet.
There are many types of malware:
Strategies:
There are two ways :
1.Protecting the enclave boundaries
2.Protecting the computing environment.
Enclave Boundaries:
Enclave Boundary is the point where the organisation interacts with internet.
Firewall: Firewall is used to access the control for inbound and outbound comunications.Various attacks will be reduced .The firewall needs to be configured for outbound network traffic.
Intrusion Detection system: It is used to identify network traffic in real time.They have signatures to detect malwars and abnormal network communications. The IDS placement is external to the organization as well as internally, just behind the firewall.
Computed Environments
Computing hardware and software from attack will be the first line of defence against the malware inside and outside.
Authorised local network devices: USB thumb-drives, MP3 players, personal or consultant laptops may be a threat ,therefore if an exception is required by business case, the owner should ensure the device is free of malware before allowed to connect to the network.
Operating systems hardening: Operating systems should be hardened to improve the ability to withstand attacks.
Anti virus updating: Anti virus updation is a very important strategy to control malware. Every updation of viruses will clean up the system particularly and prevent by network malwares.
Change control process: A change control has to be processed for the document and review firewall and other network changes before they are implemented.
Host based firewall: These are  helpful to identify applications that may have been trojanized after initial installation. It is also used to validate the application.
Vulnerability scanning:It is used to scan results in which hosts are vulnerable of various attacks.
.
It's Your Move: The Changing Game of Endpoint Security
The document discusses challenges in modern endpoint security and strategies to address them. It outlines how attackers have changed their tactics to take advantage of outdated defenses. The key moves discussed to regain control include implementing defense-in-depth endpoint security, shifting to trust-based security focused on preventing execution rather than detection, focusing on operational basics like patching and asset management, and managing devices to limit local admin risks and unwanted applications. It also provides an example of how one company addressed their security issues by implementing the Lumension Endpoint Management and Security Suite.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
