What is SIDE-CHANNEL ATTACK? What does SIDE-CHANNEL ATTACK mean? SIDE-CHANNEL ATTACK meaning - SIDE-CHANNEL ATTACK definition - SIDE-CHANNEL ATTACK explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, a side-channel attack is any attack based on information gained from the physical implementation of a cryptosystem, rather than brute force or theoretical weaknesses in the algorithms (compare cryptanalysis). For example, timing information, power consumption, electromagnetic leaks or even sound can provide an extra source of information, which can be exploited to break the system. Some side-channel attacks require technical knowledge of the internal operation of the system on which the cryptography is implemented, although others such as differential power analysis are effective as black-box attacks. Many powerful side-channel attacks are based on statistical methods pioneered by Paul Kocher. Attempts to break a cryptosystem by deceiving or coercing people with legitimate access are not typically called side-channel attacks: see social engineering and rubber-hose cryptanalysis. For attacks on computer systems themselves (which are often used to perform cryptography and thus contain cryptographic keys or plaintexts), see computer security. The rise of Web 2.0 applications and software-as-a-service has also significantly raised the possibility of side-channel attacks on the web, even when transmissions between a web browser and server are encrypted (e.g., through HTTPS or WiFi encryption), according to researchers from Microsoft Research and Indiana University. General classes of side channel attack include: Cache attack — attacks based on attacker's ability to monitor cache accesses made by the victim in a shared physical system as in virtualized environment or a type of cloud service. Timing attack — attacks based on measuring how much time various computations take to perform. Power-monitoring attack — attacks that make use of varying power consumption by the hardware during computation. Electromagnetic attack — attacks based on leaked electromagnetic radiation, which can directly provide plaintexts and other information. Such measurements can be used to infer cryptographic keys using techniques equivalent to those in power analysis or can be used in non-cryptographic attacks, e.g. TEMPEST (aka van Eck phreaking or radiation monitoring) attacks. Acoustic cryptanalysis — attacks that exploit sound produced during a computation (rather like power analysis). Differential fault analysis — in which secrets are discovered by introducing faults in a computation. Data remanence — in which sensitive data are read after supposedly having been deleted. Row hammer — in which off-limits memory can be changed by accessing adjacent memory. Optical - in which secrets and sensitive data can be read by visual recording using a high resolution camera, or other devices that have such capabilities (see examples below). In all cases, the underlying principle is that physical effects caused by the operation of a cryptosystem (on the side) can provide useful extra information about secrets in the system, for example, the cryptographic key, partial state information, full or partial plaintexts and so forth. The term cryptophthora (secret degradation) is sometimes used to express the degradation of secret key material resulting from side-channel leakage. A cache side-channel attack works by monitoring security critical operations such as AES T-table entry or modular exponentiation multiplicand accesses. Attacker then is able to recover the secret key depending on the accesses made (or not made) by the victim, deducing the encryption key. Also, unlike some of the other side-channel attacks, this method does not create a fault in the ongoing cryptographic operation and is invisible to the victim.

Internet hackers can steal our bank details from our computers and can reduce our bank balance from 1000s of dollars to 0 in seconds. So, firewall is must in a computer / computer network. Starting with packet filtering firewall. Suppose, I am downloading a file from internet. When the data-packet arrives a packet-filtering firewall, it only checks sender’s and receiver’s IP address and the port number. If the everything is OK, then data packet is allowed to pass through packet-filtering firewall and then to my computer. This checking process is done as per rules written in a list called access control list. The only limitation (caveats) of packet filtering firewall is that it do not checks the data portion, i.e. Payload, of the data packet. So, a hacker could send some malicious data packed in this payload section. The 2nd one is application / proxy firewall: proxy firewall do not let the web server know which computer actually wants to visit the requested website, i.e. proxy firewall hides us from the attackers in internet. Since, the application firewalls also check the data contents of the received data packet so they are generally much slower than packet-filtering firewalls. 3rd is Hybrid firewalls: Hybrid firewalls combines packet filtering firewall and application firewall in series to enhance the security. If they are connected in parallel then the security of the connection will be reduced to the parameters defined by the packet filtering firewall, i.e. application firewall will be of no use if the two firewalls are connected in parallel. For this reason, hybrid firewalls use packet filtering and application firewall in series. -~-~~-~~~-~~-~- Please watch: "Computer Network Administrator – 5 Important Questions and answers" https://www.youtube.com/watch?v=4mKcQ1_vQjc -~-~~-~~~-~~-~-

Network and Cyber/Web security lecture/ tutorial Types of attack (Passive Attack) by sanjay pathak There are two types of attack 1 Passive attack 2 Active Attack In Passive attack, the objective of the attacker is just to obtain the information. In the passive attack, the system works in the normal condition while message, send or receive may be affected. The passive attack is difficult to detect as there is no change of data. Example of passive attack is packet sniffing or traffic analysis. it is feasible to prevent passive attack by means of encryption.

IT Security II Attacks and Malware
 
58:25
In this video, we cover the principles of attacks and malware. We begin with an examination of malware in its various forms. Each of these forms fits either a purpose of an attack or a type of vulnerability. The forms covered include worms, viruses, Trojan horses, backdoors, and logic bombs as common attack vector agents. Adware, spyware, and ransomware characterize malware aimed for a particular purpose. The more advanced and complex forms of rootkits, botnets, polymorphic, and armored malware are also covered. We also discuss a wide array of current attack patterns. From denial-of-service and distributed denial-of-service, to spoofing, pharming, and privilege escalation, these forms of attack are technical means to an end. Man-in-the-middle, phishing, spear phishing, vishing, spam, and spim are other avenues to achieve the delivery of the malware discussed.

Cryptography basics: What is Encryption and Decryption
 
06:45
Get Full Course: http://www.engineeringmentor.com/CNYTv3 Networks #3: This tutorial introduces the Cryptography basics. It also explains what is Encryption and Decryption. a) Cryptography basics (00:21):http://youtu.be/BEb_AnPWPwY?t=21s how do we provide this security during transmission? Well, One way of ensuring security can be use of CRYPTOGRAPHY! Cryptography is a field of network security which deals with hiding "real" infromation when it is under transmission between the two parties. Usually, the real information is transformed or hidden into another message and transmitted over the network. This transformed message in itself will make no sense even if any hacker gets hold of this information. When it reaches the destination, the receipent will know a method to de-transform the garbage message into the original information which the sender had sent.method of transforming message at sender's side and de transforming at reciever's side forms the basic model of Cryptography. b) Encryption and Decryption (3:57):http://youtu.be/BEb_AnPWPwY?t=3m57s First, the information to be transmitted, called as plain text(or message) is fed to an Encryption system. The Encyrption system uses a key to convert the plain text to encyrpted form which looks like garbage value. This is also called as cipher text. A corresponding key is used at the other end to decrypt the cipher text back to original message. When we say a key, it actually means a piece of string value which is fed to encyprtion and decryption algorithms along with the text for transformation. When the message reaches the destination, this system at the other end decrypts the cipher text into original message with the help of the key. This is called as Decryption System. The output of the Decryption System is the intended message. Depending on how the keys are shared, we can classify crytography as symmetric and asymmetric. If the keys used by both parties are same, then it is called symmetric key cryptography, or private key cryptography. If both parties use different keys for encyrption and decryption, then it is called asymmetric key cryptography or public key cryptography. video URL : https://www.youtube.com/watch?v=BEb_AnPWPwY Watch ALL CN VIDEOS: https://www.youtube.com/playlist?list=PL9OIoIp8YySF4mkIihOb_j2HZIRIlYuEx For more, visit http://www.EngineeringMentor.com Facebook: https://www.facebook.com/EngineeringMentor Twitter : https://twitter.com/Engi_Mentor

The Different Types of Crypto Wallets
 
14:37
In response to ash368 here is my roundup of the many different types of crypto wallet. I try and give an outline of the main types along with the pros and cons of each type. As always feel free to ask any questions in the comments below. Online Wallets An online wallet is a cryptocurrency wallet that you access via your web browser. They are the easiest type of wallet to create, however in most situations you don't control your private keys, although there are exceptions. In this discussion I'm going to also lump exchanges in with online wallets. There are also incredibly attractive to hackers and they work much harder to get money from them. It happens, you’ve been warned. Just look at the Mt Gox hack. Advantages: - Ideal for holding small amounts of cryptocurrency for trading - Some are able to manage multiple cryptocurrencies, transfer amounts between them, or be directly integrated into an exchange Disadvantages: - Users are susceptible to phishing scams, malware, insider hacking, DDOS attacks, and outdated security measures - Your wallet is "out of your hands" and coin information is stored on a third-party - Your computer is open to malware, keyloggers, and viruses. Examples: Exchanges like Bittrex or Poloniex, and online wallets like MyEtherWallet.com and MyMonero.com. Software Wallets A software wallet is considered somewhat more secure than online wallets, however that depends on your commitment to online security. You have to download a software wallet onto your desktop or mobile and in the case of QT wallets completely download and sync the blockchain which can often take a long time, although there are light wallets like electrum which don't require you to download the blockchain. In cases where you use an old laptop, completely offline, on a clean operating system install – you could consider this a really effective cold storage method. Like phones, a lot of people have an older laptop floating around and this could be a great use for it. Advantages: - Generally fairly easy to use - Private keys not stored on a third-party server - TOR network or VPN can be used for more privacy Disadvantages: - If connected to the internet there are security and privacy caveats - If you forget to back it up and your HD fails you'll lose your coins - Your computer is open to malware, keyloggers, and viruses Examples: Exodus, Bitcoin Core, Any QT wallet for desktop or stuff like Copay and MyCelieum on mobile. Hardware Wallets Hardware wallets are a perfect solution for long term cold storage of large amounts of cryptos which you don't need day-to-day access to. There are also very secure. Advantages: - If it has a screen, it’s the most secure way to store crypto long-term - Stronger security than all other wallets, for the most part Disadvantages: - Cumbersome for some beginners to use, but an absolute must for large quantities of cryptocurrencies - Often sold out, but if you perservere you'll get one Examples: Ledger, Trezor and KeepKey are really great solutions. Paper Wallets Before there were hardware wallets, paper wallets were the defacto standard for cold storage of cryptocurrencies. They consist of a private key and a bitcoin address, often with QR codes for easy import. Advantages: - One of the most hacker-proof crypto wallet choices - Not stored on a computer - Private keys not stored on a third party server Disadvantages: - More effort required to move cryptocurrencies around - More technical understand required Examples: BitAddress.org and Bitcoin Armory can help you create and print your paper wallet. Buy $100 of Bitcoin, Ethereum or Litecoin on Coinbase and get $10 free: https://www.coinbase.com/join/591341440c80e2008c65fb8f Tips are much appreciated, here's my addresses: Bitcoin: 18ZwmG5o2yeiUW7WgLB2M8ifMK7AAmgsUs Ethereum: 0x039D99c841fc21d8975aB8691bF6B7540c06389F Litecoin: LiDRt5ZkNSX1kUT2SPg9hyirdFji8pkXeR Dash: Xrk1QLtZMPN7BBQewmGHwW2e2AGraLV3Qx Dogecoin: DKj7UeXXzQy3KwakNLfoaWm8YAQaCa8pTa Burstcoin: BURST-CMCH-2BAS-BS5A-57T5M Digibyte: DLmApKQjqC1tMgMKitwtFL8hubgTjfU2cR
