OWASP Proactive Controls: the answer to the OWASP Top Ten Kerr Ventures

By Education

In this blog post, I’ll discuss the importance of establishing the different components and modules you’ll need in your project and how to choose frameworks and libraries with secure defaults. Two great examples of secure defaults in most web frameworks are web views that encode output by default (providing XSS attack defenses) as well as built-in protection against Cross-Site Request Forgeries. Sometimes though, secure defaults can be bypassed by developers on purpose. So, I’ll also show you how to use invariant enforcement to make sure that there are no unjustified deviations from such defaults across the full scope of your projects. It’s important to carefully design how your users are going to prove their identity and how you’re going to handle user passwords and tokens.

Let’s explore each of the OWASP Top Ten, discussing how the pieces of the Proactive Controls mitigate the defined application security risk. As a general rule, only the minimum data required should be stored on the mobile device. But if you must store sensitive data on a mobile device, then sensitive data should be stored within each mobile operating systems specific data storage directory.

Implement Security Logging and Monitoring¶

Security requirements are derived from industry standards, applicable laws, and a history of past vulnerabilities. Security requirements define new features or additions to existing features to solve a specific security problem or eliminate a potential vulnerability. OWASP Top 10 Proactive Controls describes the most important control and control categories that every architect and developer should absolutely, 100% include in every project.

A subject is an individual, process, or device that causes information to flow among objects or change the system state. The access control or authorization policy mediates what subjects can access which objects. A prominent OWASP project named Application Security Verification Standard—often referred to as OWASP ASVS for short—provides over two-hundred different requirements for building secure web application software. In this series, I’m going to introduce the OWASP Top 10 Proactive Controls one at a time to present concepts that will make your code more resilient and enable your code to defend itself against would-be attackers.

C4: Encode and Escape Data

Cryptographic failures are breakdowns in the use of cryptography within an application, stemming from the use of broken or risky crypto algorithms, hard-coded (default) passwords, or insufficient entropy (randomness). A broken or risky crypto algorithm is one that has a coding flaw within the implementation of the algorithm that weakens the resulting encryption. A risky crypto algorithm may be one that was created years ago, and the speed of modern computing has caught up with the algorithm, making it possible to be broken using modern computing power.

  • This includes making sure no sensitive data, such as passwords, access tokens, or any Personally Identifiable Information (PII) is leaked into error messages or logs.
  • In the Snyk app, as we deal with data of our users and our own, it is crucial that we treat our application with the out-most care in terms of its security and privacy, protecting it everywhere needed.
  • Just as business requirements help us shape the product, security requirements help us take into account security from the get-go.
  • The first rule of sensitive data management is to avoid storing sensitive data when at all possible.

The Top 10 Proactive Controls are by developers for developers to assist those new to secure development. The first rule of sensitive data management is to avoid storing sensitive data when at all possible. If you must store sensitive data then make sure it’s cryptographically protected in some way to avoid unauthorized disclosure and modification. Database injections are probably one of the best-known security vulnerabilities, and many injection vulnerabilities are reported every year. In this blog post, I’ll cover the basics of query parameterization and how to avoid using string concatenation when creating your database queries. After the need is determined for development, the developer must now modify the application in some way to add the new functionality or eliminate an insecure option.

Data Classification¶

Each data category can then be mapped to protection rules necessary for each level of sensitivity. For example, public marketing information that is not sensitive may be categorized as public data which is ok to place on the public website. Credit card numbers may be classified as private user data which may need to be encrypted while stored or in transit. Snyk interviewed 20+ security leaders who have successfully and unsuccessfully built security champions programs. Check out this playbook to learn how to run an effective developer-focused security champions program.

As software developers author the code that makes up a web application, they need to embrace and practice a wide variety of secure coding techniques. All tiers of a web application, the user interface, the business logic, the controller, the database code and more – all need to be developed with security in mind. This can be a very difficult task and developers are often set up for failure. The languages and frameworks that developers use to build web applications are often lacking critical core controls or are insecure by default in some way. It is also very rare when organizations provide developers with prescriptive requirements that guide them down the path of secure software.

On Android this will be the Android keystore and on iOS this will be the iOS keychain. Cryptography (or crypto) is one of the more advanced topics of information security, and one whose understanding requires the most schooling and experience. It is difficult to get right because there are many approaches to encryption, each with advantages and disadvantages that need to be thoroughly understood by web solution architects and developers.

A user story focuses on the perspective of the user, administrator, or attacker of the system, and describes functionality based on what a user wants the system to do for them. The ASVS requirements are basic verifiable statements which can be expanded upon with user stories and misuse cases. The advantage of a user story or misuse case is that it ties the application to exactly what the user or attacker does to the system, versus describing what the system offers to the user. The OWASP Application Security Verification Standard (ASVS) is a catalog of available security requirements and verification criteria.

A06 Vulnerable and Outdated Components

This approach is suitable for adoption by all developers, even those who are new to software security. The OWASP Top Ten Proactive Controls 2018 is a list of security techniques that should be considered for every software development project. This document is written for developers to assist those new to secure development.

WLUNA vs LUNC: How Can Investors and Traders Benefit from These Terra Tokens?

By Cryptocurrency News

There is a theory that the additional term “classic” is a reference to the Ethereum / Ethereum Classic split in 2017. According to CEO, Do Kwon, the collapse of UST in the spring of 2022 is the equivalent moment of the Ethereum’s DAO hack that took place in 2017. LUNC is a token on the Terra network, while WLUNA is an ERC20 token representing LUNC on the Ethereum network.

  • In the Binance Luna 2.0 support announcement, it said it would resume LUNC trading on May 30.
  • Both versions of the token have the right to exist as a result of the implementation of a proposal called Terra Ecosystem Revival Plan 2.
  • The concurrent rise in all the Terra-backed tokens comes primarily as a result of the revoking of the Terra founder’s extradition.
  • In the same manner, airdrops can be used to reimburse funds, or at least provide an opportunity for an imbursement.
  • This is done through minting and burning the supply and demand of the coin.
  • Before the crisis, UST, Terra’s stablecoin, had a market value of more than $18bn.

Bitcoin, Bitcoin Cash, Ethereum, Litecoin and other popular cryptocurrencies can be purchased with U.S. dollars using Coinbase. Once you have purchased Bitcoin using Coinbase, you can then transfer your Bitcoin to an exchange such as Binance to purchase other cryptocurrencies, including Terra Classic. The primary real-world impact of LUNC burn is that it aims to increase LUNC value by decreasing its supply. With fewer tokens in circulation, each token inherently becomes more valuable. Over time, this mechanism creates a deflationary pressure that helps to boost LUNC value. For token holders, this means that the value of their holdings could potentially increase over time, leading to financial gain.

One of these is its open interest, which has been dropping for the past week as prices started falling. Proposal “Burn of 800m USTC Funds” is up for voting on the Station wallet. The proposal aims to burn the 800 million USTC still in the Risk Harbor multisig wallet via a contract. In a related decision, the Appeals Court had previously rescinded a ruling by the Higher Court that postponed Do Kwon’s extradition until he completed a prison sentence for a separate offense. According to a statement on the 19th of December, the Appellate Court found a significant violation of criminal procedure in the lower court’s decision. As a result, Kwon’s extradition to countries South Korea and the U.S. were promptly revoked.

LUNC Price Chart

Massive amounts of UST were sold off in mass panic, having a knock-on effect on LUNA price, which crashed. Terra platform is developed using the Cosmos blockchain technology and is introduced to challenge incumbent retail payment applications. Looking at the positives, Terra Luna Classic could have the potential to offer gains for investors, depending on the length of investment and reactions.

  • There is a theory that the additional term “classic” is a reference to the Ethereum / Ethereum Classic split in 2017.
  • Each transaction is subject to (on average) a 2%–3% fee charged to the merchant.
  • Always conduct your own due diligence before trading, looking at the latest news, a wide range of analyst commentary, technical and fundamental analysis.
  • Proposal “Burn of 800m USTC Funds” is up for voting on the Station wallet.

Before buying LUNC on any exchange, we recommend you research and compare the fees, security measures, and user reviews of different exchanges to find the one that best suits your needs. Once you choose an exchange, you can create an account, complete the necessary verification steps, and deposit funds to buy LUNC. LUNA was launched in 2018 and is the primary token used for staking and governance for the Terra network. Since the collapse of LUNA and UST in mid-May, most investors have lost faith in the Terra community.

Leading Cryptocurrencies

As we look to the future, it’s clear that LUNC has a promising road ahead. The innovative burn mechanism, coupled with a resilient community and a dedicated team, paints a bright picture for Luna Classic’s future. While the journey may be fraught with challenges, the potential rewards are substantial.

Those concerned about the tokenomics of this beaten-down project now have a catalyst to jump on today. Given the rather complex restructuring that’s still ongoing with the Terra Classic blockchain, there’s plenty of room for speculation around this token. Accordingly, investors had seen previous rallies in this token that many have attributed to the equivalent of meme rallies in recent weeks. Indeed, some holders bought more Luna Classic in the lead up to the new chain. The Luna 2.0 airdrop of new tokens included an allocation for existing Luna holders.

The goal of this burn tax is to ultimately reduce Terra’s bloated supply of its LUNC token from 6.9 trillion to around 20 billion. That said, such burns are meaningless if crypto exchanges do not engage. The introduction of the Terra Classic platform empowered the price-stable global payment systems and made trading and investment much more secure. Terra’s native token, LUNC can be purchased from exchanges such as Binance, KuCoin, Huobi Global,, MEXC, Kraken, and V2.

LUNC in the Future: Predictions and Possibilities

The abrupt collapse of the Terra ecosystem in May 2022 was a ‘black swan’ event, with damaging consequences for its investors and the whole cryptocurrency community. In the same manner, airdrops can be used to reimburse funds, or at least provide an opportunity for an imbursement. On May 28, Do Kwon’s revival proposal spawned Terra 2.0, creating LUNA tokens on a hard-forked chain, while the original LUNA were renamed LUNA Classic (LUNC). If UST went over the one-to-one peg against the dollar, LUNA tokens were burned to mint UST in equal value. Because this increased UST supply, it brought down its value back to the USD peg.

The majority of the investors consider LUNC better and safer due to the launch of a completely new network and adaptation of the PoS mechanism. Terra Classic wallet can be used to store the LUNC token which safeguards the token using public and private keys. These wallets make it easy for the buyer to store and use the purchased tokens for different purposes. On the flip side, the value of LUNA can also decrease if UST is perceived as unstable.

LUNC in practice LUNA serves as a stabilizer that captures rewards through seigniorage and transaction fees. Using UST as an example, when the value of the stablecoin is below $1, users can artificially destroy one UST to get $1 worth of LUNA. When the value rises above $1, users can burn $1 worth of LUNA to get one UST, collecting seigniorage in the process. Through this process LUNA can regulate the relative scarcity of UST and thus maintain the value of the Terra stablecoin, allowing it to function closer to that of a fiat currency. LUNA is also used to validate Terra transactions and stakers can earn transaction fees from the protocol.

One should not pour life savings into experimental financial platforms, especially ones that rely on algorithmic stablecoins. In a mature crypto ecosystem, they may work robustly, but not in an incipient ecosystem. As a part of the recovery plan, the V22 upgrade provides LUNC token holders an opportunity to recover some of the funds lost in May’s implosion. The update enabled 1.2% burn tax whenever LUNC tokens are burned to mint UST (also rebranded to USTC). Airdrops are very flexible vehicles to market blockchain projects, create media hype and reinvigorate a stagnant protocol with new incentives.
