Secure Web Browsing Using Lightweight Portable Security

Stop for a moment and ask yourself just how safe to do feel when logging into your favorite social network site and at some point in time logging into online banking for example. I am not advocating that social networks fall short in the area of security but the reality is the internet is a dangerous place.

Today’s threats are increasing with each passing day and I would go so far to say that many individuals do not understand nor take the time to properly address security. In fact the Software Engineering Institute at Carnegie Mellon states:

  1. Many users have a tendency to click on links without considering the risks of their actions.
  2. Web page addresses can be disguised or take you to an unexpected site.
  3. Many web browsers are configured to provide increased functionality at the cost of decreased security.
  4. New security vulnerabilities may have been discovered since the software was configured and packaged by the manufacturer.
  5. Computer systems and software packages may be bundled with additional software, which increases the number of vulnerabilities that may be attacked.
  6. Third-party software may not have a mechanism for receiving security updates.
  7. Many web sites require that users enable certain features or install more software, putting the computer at additional risk.
  8. Many users do not know how to configure their web browsers securely.
  9. Many users are unwilling to enable or disable functionality as required to secure their web browser.

Each of these points demonstrate the need for a mechanism that the average person can utilize to reduce the risk across the internet. Going back to the example of online banking, what would you say if you could simply boot off a DVD into a Linux Operating system and protect you credentials? This is entirely possible with Lightweight Portable Security (LPS) which was developed by the United States Air Force.

Lightweight Portable Security

LPS differs from traditional operating systems in that it isn’t continually patched. LPS is designed to run from read-only media and without any persistent storage. Any malware that might infect a computer can only run within that session.

LPS is updated on a regular basis (at least quarterly patch and maintenance releases). Update to the latest versions to have the latest protection.

For those that are not familiar with Linux there is nothing to fear. Go grab yourself a download of Lightweight Portable Security (LPS) and see for yourself just how easy LPS is and protect yourself at the same time.

Secure Development Series: Input Validation

Many websites today collect data from the user community which includes but not limited to an email address, address, or even a phone number. The single golden rule everyone must follow is never trust the data input. In order to mitigate the risk to ensure that the data received and processed by your application is acceptable you must first define what data your application should accept, what its syntax should be and the minimum and maximum lengths. This information will allow you to define a set of “acceptable” values for every entry data point that is captured.

Foundation of Security

Foundation of Security

  1. Authentication: Addresses the question: who are you? It is the process of uniquely identifying the clients of your applications and services.
  2. Authorization: Addresses the question: what can you do? It is the process that governs the resources and operations that the authenticated client is permitted to access.
  3. Auditing:Effective auditing and logging is the key to non-repudiation. Non-repudiation guarantees that a user cannot deny performing an operation or initiating a transaction.
  4. Confidentiality: Referred to as privacy, is the process of making sure that data remains private and confidential, and that it cannot be viewed by unauthorized users or eavesdroppers who monitor the flow of traffic across a network.
  5. Integrity: The guarantee that data is protected from accidental or deliberate (malicious) modification. Like privacy, integrity is a key concern.
  6. Availability: From a security perspective, availability means that systems remain available for legitimate users.

Two main approaches exist for input validation which are called whitelisting and blacklisting.

Whitelist

A term used to describe a list or register of entities that, for one reason or another, are being provided a particular privilege, service, mobility, access or recognition. As a verb, to whitelist can mean to authorize access or grant membership. Conversely, blacklist is a term used to describe a list or compilation that identifies entities that are denied, unrecognised, or ostracised.

Blacklist

A list or register of entities who, for one reason or another, are being denied a particular privilege, service, mobility, access or recognition. As a verb, to blacklist can mean to deny someone work in a particular field, or to ostracize a person from a certain social circle. Conversely, a whitelist is a list or compilation identifying entities that are accepted, recognized, or privileged.

Both blacklisting and whitelisting are valuable tools when it comes to data validation. Typically the best approach is to adopt whitelisting and define what type of data is acceptable where blacklisting is defining data types that are unacceptable. Think about it, if you’re collecting an email address does it not make sense to address the acceptable data entry rather than what is unacceptable?

A simple regular expression used for whitelisting an email address:

^[w-]+(.[w-]+)*@([a-z0-9-]+(.[a-z0-9-]+)*?.[a-z]{2,6}|(d{1,3}.){3}d{1,3})(:d{4})?$

Matches a valid email address including ip’s which are rarely used. Allows for a-z0-9_.- in the username, but not ending in a full stop i.e user.@domain.com is invalid and a-z0-9- as the optional sub domain(s) with domain name and a 2-7 char (a-z) tld allowing for short tld’s like ca and new ones like museum.

The blacklisting approach is often avoided where possible because it only protects against threats the developer could think of at the time of its creation. This means the blacklist might miss new attack vectors and have higher maintenance costs when compared to a whitelist.

Input Validation best practices:

  • Apply whitelists (known good values) where possible.
  • Check for content (i.e. 0-9), minimum and maximum lengths and correct syntax of all inputs.

Obviously, there is a great deal of different kinds of data types that must be validated. But where does this data get into your program? The answer is from a surprising number of places; in fact, your application may be collecting data from a would be attacker in ways you weren’t prepared for or maybe have not even considered.

Financial Industry Modern Day Privacy Policies

 

Financial Privacy & Electronic Commerce: Who’s In My Business, this is the question. The financial industry whether banking, investments, or credit card services face an ever changing landscape when it comes to privacy and if they are to safeguard themselves and their consumers a proper plan must be implemented. There are a number of challenges surrounding privacy in terms of data protection, consumer confidence, supplier partnerships, and of course laws and regulations. The financial industry is particularly at risk because of the nature of business as well as the utter amount of transactions and the sizable customer base. Not only does the Internet pose what is likely the single largest risk in the realm of privacy but also traditional communications must accurately address privacy.

To set the stage of what privacy exemplifies the Webster dictionary defines privacy as the quality or state of being apart from company or observation. Now that the definition of privacy is clear, the financial industry must account for laws and regulations in order to both safeguard themselves and their customers. To address privacy it is imperative to establish a policy, which outlines the steps of how a bank manages and shares personal information. Many banks will use personal information to increase partnerships, provide a good or service, or even to assist in protection against fraud and identity theft. At this point, the scope of privacy begins to take form.

Over the years, a business typically used paper-based statements and communications to convey information but modern day, the Internet has improved the legacy business model. While the Internet has not entirely substituted the legacy model, it does offer convince for consumers and at the same time helps to diminish cost for a business, at least in terms of traditional mailers. Of course, the Internet opens the door to hackers who can exploit vulnerabilities as well as take advantage of the population that does not practice concrete security practices. In order to properly address privacy then the financial industry must abide by laws and regulations while also sharing in the responsibility of education for suppliers, partners, and consumers.

This article will take a deeper dive into the financial industry in terms of a comparison and contrast as well as recommendations in the area of change that must occur.

Organization and Mission

The banking industry exists to serve customers from individuals, corporations, and groups. The role of a bank is to facilitate in the end goal of financial freedom and investments. The banking industry also serves a staple in both the United States and global economies that in turn drive a robust need of regulations and laws. Typically, a mission statement may include:

  1. Provides best of breed financial services
  2. Accountability to shareholders and customers

By nature the banking industry is at abundant risk solely due to the utter amount of sensitive data from the customer is enormous. The details of personal information and daily transactions drive stout concerns from customers from both a privacy and security point of view.

Privacy Policy and Laws

The Federal Deposit Insurance Corporation (FDIC) is in place to aid in the protection of the privacy of participants and the overall banking industry. The FDIC commonly provides both high and low level guidance in the area of financial activities and operations, and in other limited circumstances such as where required for law enforcement and public disclosure activities. In addition, the minimum necessary information will be used, except in limited situations specified by applicable law. Other uses and disclosures of financial transactions will not occur unless the customer authorizes them. Customers will have the opportunity to inspect, copy, and amend their privacy elections as required by both existing laws and regulations. Privacy is extremely important within the financial industry. Customers may also exercise the rights granted to them under these same laws and regulations free from any intimidating or punitive acts. The public in general is becoming much more educated and aware of the risk of personal information as well how all facets of business and how they share information, because of this there are two fundamental principles:

  1. Establish both initial and annual privacy policies
  2. Provide a mechanism for customers to opt in or opt out with information sharing

There are established acts that allow banks to share customer information and once such act is the Gramm-Leach-Bliley Banking Modernization Act of 1999. Oddly enough, the Gramm-Leach-Bliley Banking Modernization Act is rooted in a case from Victoria’s Secret. In this case, Representative Joe Barton of Texas felt that his credit union had disclosed his address to Victoria’s Secret even though he had not established a business relationship with Victoria’s Secret. As we turn our attention to the scope of technology and the variety of usage it brings to the table, it becomes apparent that technology helps in everyday life activities but at the same time, this same technology has unmistakably broken down other aspects of privacy.

Policy and Law Changes

Amazon Image The single largest challenge within the financial industry may be how privacy is addressed in terms of business and the end consumers. While there are both modern and historical laws and regulations, they often conflict one another or worse leave open opportunities that are easily exploited or maybe even entirely overlooked. The banking industry as a whole is doing a much better job surrounding privacy but as technology and business partnerships continue to evolve, so does the need to address current policies and laws.

Data collection and sharing has become ever so important in terms of conducting business to the degree that ethics becomes center place. Over two decades ago, four issues of ethics arose from the information age and a new acronym was born called PAPA which calls out privacy, accuracy, property, and accessibility. The challenge is to take all existing laws, whether at state or federal level and balance these laws across the banking industry while keeping in mind the needs of the business and most importantly the customers.

Individual Rights

All consumers must have the right to access, inspect, and copy his or her information within accordance to policy and laws. The banking industry generally must honor these rights, except in certain circumstances when the information may result is a breach of privacy that a spouse or family member is allowed to under applicable laws. Once consumers begin to understand their rights, only then will they be in a better position to both protect them and self-police the banking industry. Of course, this is easier said than done. Most consumers are provided privacy information from the financial vendor in which they conduct business but the information is confusing at best. Stop and consider for a moment the process a consumer undergoes when opening a checking account with a bank. The bank adheres to laws and provides a privacy statement but more often than not, these same privacy statements are written in legal terms rather that common everyday language. The Federal Trade Commission (FTC) plays a vital role between consumers and industries. Overall, the FTC performs as to expectations in terms of consumer protection and one such example is the Fair Information Practice Act of 1997. This act outlines five core principles:

  1. Notice and Awareness
  2. Choice and Consent
  3. Access and Participation
  4. Integrity and Security
  5. Enforcement and Redress
  6. Liability

Should banks not conform to laws and regulations the results it can be disastrous to the industry itself but more importantly it has the potential to destroy personal financial freedoms. For example, Chase Manhattan Bank was charged with selling their customers purchase history and an agreement was reached in 2000 with the New York State Attorney General’s office. There are many other cases, which relate directly to the Chase Bank infraction that driven the need for strong penalties when the area of privacy is violated. To better understand the liabilities surrounding privacy, one must first understand the measures of protection, which may include:

  1. Implement a clean desk practice. Personal Identifiable Information (PII) must be put away if the employee is away from his or her desk throughout the day and PII will be placed in closed and locked drawers or cabinets when the employee is not in the office.
  2. PII in paper format will be destroyed when it is obsolete or is not required to be retained for storage purposes, with shredding the preferred method of destruction.
  3. Limit the substance of PII in conversations with partners and other outside vendors to the required minimum necessary.
  4. Implement reasonable measures to prevent other individuals from overhearing conversations, e.g., using speakerphone only when in a closed office.
  5. Limit remote access to systems to secure methods.

By starting with these five points, the groundwork starts to take shape and a clear understanding of risks begins to bubble up to the surface. As risks are identified and categorized only then can the liability start to be reduced by taking these risks and build out strong policies and procedures. In the case where a bank is conducting business over the Internet, The Federal Reserve Board (FRB) has established guidelines where additional disclosure rules are needed to both protect consumers and reduce the liability of the company in question.

Risk Management

The areas of managing risks are mutual by both the financial industry as well as consumers and each must participate in certain risk management activities to ensure compliance. The business has the greatest responsibility and because of this, there are numerous opportunities when it comes to reducing risk.

  1. Workforce training on the Policies and Procedures
  2. Developing a complaint process for individuals to file complaints
  3. Designing a system of written disciplinary policies and sanctions
  4. Mitigating damages resulting from improper use or disclosure
  5. Retaining copies of its Policies and Procedures, written communications, and actions

Some of these risk management rules require stakeholders to design processes affecting employees under their control.

Complaints

Banks must have an established process to process a person’s complaint about the privacy policies and procedures, practices, and compliance. The resolution of complaints depends on the varying facts and circumstances of the complaint. Examples of viable complaint resolution include:

  1. Educating the consumer
  2. Implementing changes in the policies, procedures, and practices
  3. Providing appropriate training for employees
  4. Issuing new communication materials both to the company and consumers

This process will assist in properly addressing consumer concerns as well as assisting banks in terms of legal obligations.

Security Implications

At the end of the day, privacy is much more than just protecting information. When a bank’s information is breached by hackers or even by the everyday nature of business, the results are extremely damaging. The criminal act of stolen identities is a billion dollar criminal enterprise and it all starts with improper privacy practices. While many countries have defined agencies that oversee privacy, the reality is these same agencies tend to be rooted in existing laws that are outdated or even must advocate the need for new laws.

Conclusion

At this point, the gravity of privacy as applied to both the banking industry and consumers should be a call to action. Banks must make every reasonable effort to protect the privacy rights and interests of consumers in the collection, use, transfer, or retention of information to prevent inappropriate or unnecessary disclosures of information.

In closing, the following is instrumental to continually understanding and measuring privacy concerns. The financial industry must make every reasonable effort to protect the privacy rights and interests of consumers and their partners to include unnecessary disclosures of information. The industry must further comply with all existing laws and regulations. Since technology has become commonplace the online privacy aspect opens another area of concern that warrants a drastic change is regulations. Of course, the challenge is the ever-changing technology landscape that typically drives parties who enact laws to move quickly but often do not fully comprehend the challenges surrounding modern day technology.
